DOI: 10.1021/AM403272Z
Abstract: A novel CO2-stable and reduction-tolerant Ce0.8Sm0.2O(2-δ)-La0.9Sr0.1FeO(3-δ) (SDC-LSF) dense dual-phase oxygen-permeable membrane was designed and evaluated in this work. Homogeneous SDC-LSF composite powders for membrane fabrication were synthesized via a one-pot combustion method. The chemical compatibility and ion interdiffusion behavior between the fluorite phase SDC and perovskite phase LSF during the synthesis process was studied. The oxygen permeation flux through the dense dual-phase composite membranes was evaluated and found to be highly dependent on the volume ratio of SDC and LSF. The SDC-LSF membrane with a volume ratio of 7:3 (SDC70-LSF30) possessed the highest permeation flux, achieving 6.42 × 10(-7) mol·cm(-2)·s(-1) under an air/CO gradient at 900 °C for a 1.1-mm-thick membrane. Especially, the membrane performance showed excellent durability and operated stably without any degradation at 900 °C for 450 h with helium, CO2, or CO as the sweep gas. The present results demonstrate that a SDC70-LSF30 dual-phase membrane is a promising chemically stable device for oxygen production and CO2 capture with sufficiently high oxygen permeation flux.
Atomically dispersed chromium coordinated with hydroxyl clusters enabling efficient hydrogen oxidation on ruthenium
Publisher: Springer Science and Business Media LLC
Date: 06-10-2022
DOI: 10.1038/S41467-022-33625-X
Abstract: Overcoming the sluggish kinetics of alkaline hydrogen oxidation reaction (HOR) is challenging but is of critical importance for practical anion exchange membrane fuel cells. Herein, abundant and efficient interfacial active sites are created on ruthenium (Ru) nanoparticles by anchoring atomically isolated chromium coordinated with hydroxyl clusters (Cr 1 (OH) x ) for accelerated alkaline HOR. This catalyst system delivers 50-fold enhanced HOR activity with excellent durability and CO anti-poisoning ability via switching the active sites from Ru surface to Cr 1 (OH) x -Ru interface. Fundamentally different from the conventional mechanism merely focusing on surface metal sites, the isolated Cr 1 (OH) x could provide unique oxygen species for accelerating hydrogen or CO spillover from Ru to Cr 1 (OH) x . Furthermore, the original oxygen species from Cr 1 (OH) x are confirmed to participate in hydrogen oxidation and H 2 O formation. The incorporation of such atomically isolated metal hydroxide clusters in heterostructured catalysts opens up new opportunities for rationally designing advanced electrocatalysts for HOR and other complex electrochemical reactions. This work also highlights the importance of size effect of co-catalysts, which should also be paid substantial attention to in the catalysis field.

Publisher: American Chemical Society (ACS)

DOI: 10.1021/AM301788M
Abstract: Porous SnO₂/graphene composite thin films are prepared as anodes for lithium ion batteries by the electrostatic spray deposition technique. Reticular-structured SnO₂ is formed on both the nickel foam substrate and the surface of graphene sheets according to the scanning electron microscopy (SEM) results. Such an assembly mode of graphene and SnO₂ is highly beneficial to the electrochemical performance improvement by increasing the electrical conductivity and releasing the volume change of the anode. The novel engineered anode possesses 2134.3 mA h g⁻¹ of initial discharge capacity and good capacity retention of 551.0 mA h g⁻¹ up to the 100th cycle at a current density of 200 mA g⁻¹. This anode also exhibits excellent rate capability, with a reversible capacity of 507.7 mA h g⁻¹ after 100 cycles at a current density of 800 mA g⁻¹. The results demonstrate that such a film-type hybrid anode shows great potential for application in high-energy lithium-ion batteries.

A Novel Perovskite Electron–Ion Conductive Coating to Simultaneously Enhance Cycling Stability and Rate Capability of Li1.2Ni0.13Co0.13Mn0.54O2 C
Publisher: Wiley
Date: 26-03-2021
Abstract: Poor cycling stability and rate capability are two key issues needing to be solved for Li‐ and Mn‐rich oxide cathode material for lithium‐ion batteries (LIBs). Herein, a novel perovskite electron–ion mixed conductor Nd 0.6 Sr 0.4 CoO 3 (NSCO) is used as the coating layer on Li 1.2 Ni 0.13 Co 0.13 Mn 0.54 O 2 (LNCMO) to simultaneously enhance its cycling stability and rate capability. By coating 3 wt% NSCO, LNCMO–3NSCO exhibits an optimal cycling performance with a capacity retention of 99% at 0.1C (1C = 200 mA g −1 ) after 60 cycles, 91% at 1C after 300 cycles, and 54% at 20C after 1000 cycles, much better than 78%, 63%, and 3% of LNCMO, respectively. Even at a high charge and discharge rate of 50C, LNCMO–3NSCO exhibits a discharge capacity of 53 mAh g −1 and a mid‐point discharge voltage of 2.88 V, much higher than those of LNCMO (24 mA h g −1 and 2.40 V, respectively). Benefiting from the high electronic conductivity (1.46 S cm −1 ) and ionic conductivity (1.48 × 10 −7 S cm −1 ), NSCO coating not only suppresses transition metals dissolution and structure transformation, but also significantly enhances electronic conductivity and Li + diffusion coefficient of LNCMO by an order of magnitude.

Tailoring Interfacial Charge Transfer of Epitaxially Grown Ir Clusters for Boosting Hydrogen Oxidation Reaction
Publisher: Wiley
Date: 06-11-2022
Abstract: The sluggish kinetics of hydrogen oxidation reaction (HOR) is one of the critical challenges for anion exchange membrane fuel cells. Here, we report epitaxial growth of Ir nanoclusters ( nm) on a MoS 2 surface (Ir/MoS 2 ) and optimize the alkaline HOR activity via tailoring interfacial charge transfer between Ir clusters and MoS 2 . The electron transfer from MoS 2 to Ir clusters can effectively prevent the oxidation of Ir clusters, which is not the case for carbon‐supported Ir nanoclusters (Ir/C) synthesized using the same method. Moreover, the HOR performance of the Ir/MoS 2 can be further optimized by tuning the hydrogen binding energy (HBE) via a precise annealing treatment. A substantial exchange current density of 1.28 mA cm ECSA −2 is achieved in the alkaline medium, which is ∼10 times over that of Ir/C. The HOR mass‐specific activity of Ir/MoS 2 heterostructure is as high as 182 mA mg Ir −1 . The experimental results and density functional theory calculations reveal that the significant improved HOR activity is attributed to the decreased HBE, which highlights epitaxial growth is an effective way for boosting catalytic activity of heterostructured catalysts.

Abstract: The use of solid-state electrolytes in all-solid-state batteries is a prospective technology for increasing energy densities. However, poor oxidative stability and issues with the dendrite significantly h er their applicability. LiBH 4 is considered as one of the most promising candidates due to its irreplaceable thermodynamic stability to Li. Herein, an in situ melting reaction is proposed to generate the covalently bonded coordination on the particle surfaces of electrolytes to resolve those issues. This coordination thermodynamically shuts down the electronic exchanges during the anionic oxidation decomposition by covalently bonding the local high-concentration electrons on the anions, and it kinetically blocks electronic percolation on the particle surfaces of electrolytes this phenomenon leads to an unprecedented voltage window (0 ~ 10 V) with a peak oxidation current that is 370 times lower and an electronic conductivity that is 3 orders of magnitude lower than the counterpart at 25 ℃. The coordination can act as a binder to bond electrolyte particles, achieving a remarkable Young’s modulus of 208.45 GPa this modulus is twice as high as the counterpart to adapt the sustained stress-strain release in Li plating and stripping. With these merits, the electrolyte displays a record-breaking critical current density of 21.65 mA cm − 2 at 25 ℃ (twice the best-reported data in Li-ion solid-state electrolytes), cycling stabilities under 10.83 mA cm − 2 for 6000 h and 10 V for 1000 h, and an operational temperature window of -30 to 150 ℃. Their Li-LiCoO 2 cells exhibit superior reversibility under high voltage. Our findings illuminate a clear direction for oxidative stability and dendrite suppression in solid-state electrolytes, making tremendous progress in high-voltage lithium batteries.

Diversity of platinum-sites at platinum/fullerene interface accelerates alkaline hydrogen evolution

DOI: 10.1038/S41467-023-37404-0
Abstract: Membrane-based alkaline water electrolyser is promising for cost-effective green hydrogen production. One of its key technological obstacles is the development of active catalyst-materials for alkaline hydrogen-evolution-reaction (HER). Here, we show that the activity of platinum towards alkaline HER can be significantly enhanced by anchoring platinum-clusters onto two-dimensional fullerene nanosheets. The unusually large lattice distance (~0.8 nm) of the fullerene nanosheets and the ultra-small size of the platinum-clusters (~2 nm) leads to strong confinement of platinum clusters accompanied by pronounced charge redistributions at the intimate platinum/fullerene interface. As a result, the platinum-fullerene composite exhibits 12 times higher intrinsic activity for alkaline HER than the state-of-the-art platinum/carbon black catalyst. Detailed kinetic and computational investigations revealed the origin of the enhanced activity to be the erse binding properties of the platinum-sites at the interface of platinum/fullerene, which generates highly active sites for all elementary steps in alkaline HER, particularly the sluggish Volmer step. Furthermore, encouraging energy efficiency of 74% and stability were achieved for alkaline water electrolyser assembled using platinum-fullerene composite under industrially relevant testing conditions.
Cobalt Single Atoms Enabling Efficient Methanol Oxidation Reaction on Platinum Anchored on Nitrogen‐Doped Carbon
Publisher: Wiley
Date: 05-2022
Abstract: Developing efficient platinum (Pt)‐based electrocatalysts with high tolerance to CO poisoning for the methanol oxidation reaction is critical for the development of direct methanol fuel cells. In this work, cobalt single atoms are introduced to enhance the electrocatalytic performance of N‐doped carbon supported Pt (N‐C/Pt) for the methanol oxidation reaction. The cobalt single atoms are believed to play a critical role in accelerating the prompt oxidation of CO to CO 2 and minimizing the CO blocking of the adjacent Pt active sites. Benefitting from the synergistic effects among the Co single atoms, the Pt nanoparticles, and the N‐doped carbon support, the Co‐modified N‐C/Pt (Co‐N‐C/Pt) electrocatalyst simultaneously delivers impressive electrocatalytic activity and durability with lower onset potential and superb CO poisoning resistance as compared to the N‐C/Pt and the commercial Pt/C electrocatalysts.

Single‐Atom Electrocatalysts for Multi‐Electron Reduction of CO2
Publisher: Wiley
Date: 09-07-2021
Abstract: The multi‐electron reduction of CO 2 to hydrocarbons or alcohols is highly attractive in a sustainable energy economy, and the rational design of electrocatalysts is vital to achieve these reactions efficiently. Single‐atom electrocatalysts are promising candidates due to their well‐defined coordination configurations and unique electronic structures, which are critical for delivering high activity and selectivity and may accelerate the explorations of the activity origin at atomic level as well. Although much effort has been devoted to multi‐electron reduction of CO 2 on single‐atom electrocatalysts, there are still no reviews focusing on this emerging field and constructive perspectives are also urgent to be addressed. Herein recent advances in how to design efficient single‐atom electrocatalysts for multi‐electron reduction of CO 2 , with emphasis on strategies in regulating the interactions between active sites and key reaction intermediates, are summarized. Such interactions are crucial in designing active sites for optimizing the multi‐electron reduction steps and maximizing the catalytic performance. Different design strategies including regulation of metal centers, single‐atom alloys, non‐metal single‐atom catalysts, and tandem catalysts, are discussed accordingly. Finally, current challenges and future opportunities for deep electroreduction of CO 2 are proposed.

Abstract: Metal-organic frameworks (MOFs) and their derivatives with well-defined structures and compositions show great potential for wide applications such as sensors, catalysis, energy storage, and conversion, etc. However, poor electric conductivity and large volume expansion are main obstacles for their utilization in energy storage, e.g., lithium-ion batteries and supercapacitors. Herein, a facile strategy is proposed for embedding the MOFs, e.g., ZIF-67 and MIL-88 into polyacrylonitrile fibers, which is further used as a template to build a 3D interconnected conductive carbon necklace paper. Owing to the unique structure features of good electric conductivity, interconnected frameworks, electroactive reservoir, and dual dopants, the obtained flexible electrodes with no additives exhibit high specific capacities, good rate capability, and prolonged cycling stability.

DOI: 10.1016/J.CLIM.2010.05.011
Abstract: Antiviral activity of natural killer (NK) cells is regulated partially through inhibitory and activating killer cell immunoglobulin-like receptors (KIR) interacting with human leukocyte antigen C (HLA-C) ligands. The highly polymorphic nature of HLA-C and KIR genes endows in iduals with erse HLA-C/KIR combinations, which may confer susceptibility to or protection against a certain challenge. We analyzed the genes encoding KIR receptors and HLA-C ligands and HLA-C/KIR combinations in patients with chronic hepatitis B and healthy subjects. We found that inhibitory receptor KIR2DL1 in combination with HLA-C2 ligand confers susceptibility to chronic hepatitis B (CHB), whereas inhibitory receptor KIR2DL3 or KIR2DL3 homozygote in the presence of HLA-C1C1 genotype shows protection against CHB. Our data reveal that inhibitory NK cell interactions are important in determining antiviral immunity and that distinct affinity inhibitory responses will exert different impact on the development of CHB.

Fast and Durable Alkaline Hydrogen Oxidation Reaction at the Electron‐Deficient Ruthenium–Ruthenium Oxide Interface
Publisher: Wiley
Date: 2023
Abstract: The slow hydrogen oxidation reaction (HOR) kinetics under alkaline conditions remain a critical challenge for the practical application of alkaline exchange membrane fuel cells. Herein, Ru/RuO 2 in‐plane heterostructures are designed with abundant active Ru–RuO 2 interface domains as efficient electrocatalysts for the HOR in alkaline media. The experimental and theoretical results demonstrate that interfacial Ru and RuO 2 domains at Ru–RuO 2 interfaces are the optimal H and OH adsorption sites, respectively, endowing the well‐defined Ru(100)/RuO 2 (200) interface as the preferential region for fast alkaline hydrogen electrocatalysis. More importantly, the metallic Ru domains become electron deficient due to the strong interaction with RuO 2 domains and show substantially improved inoxidizability, which is vital to maintain durable HOR electrocatalytic activity. The optimal Ru/RuO 2 heterostructured electrocatalyst exhibits impressive alkaline HOR activity with an exchange current density of 8.86 mA cm −2 and decent durability. The exceptional electrocatalytic performance of Ru/RuO 2 in‐plane heterostructure can be attributed to the robust and multifunctional Ru–RuO 2 interfaces endowed by the unique metal–metal oxide domains.

Alloy‐Based Anode Materials toward Advanced Sodium‐Ion Batteries
Publisher: Wiley
Date: 28-06-2017
Abstract: Sodium-ion batteries (SIBs) are considered as promising alternatives to lithium-ion batteries owing to the abundant sodium resources. However, the limited energy density, moderate cycling life, and immature manufacture technology of SIBs are the major challenges hindering their practical application. Recently, numerous efforts are devoted to developing novel electrode materials with high specific capacities and long durability. In comparison with carbonaceous materials (e.g., hard carbon), partial Group IVA and VA elements, such as Sn, Sb, and P, possess high theoretical specific capacities for sodium storage based on the alloying reaction mechanism, demonstrating great potential for high-energy SIBs. In this review, the recent research progress of alloy-type anodes and their compounds for sodium storage is summarized. Specific efforts to enhance the electrochemical performance of the alloy-based anode materials are discussed, and the challenges and perspectives regarding these anode materials are proposed.

DOI: 10.1007/S40243-020-00170-W
Abstract: Electrochemical water splitting driven by renewable energy-derived electricity is considered as the most promising pathway for delivering clean and sustainable hydrogen production. The key to achieving an efficient water splitting process is developing highly active electrocatalysts. Two-dimensional (2D) nanomaterials hold great promise in the electrocatalysis field due to their unique physicochemical properties. Some of them are not active enough because of the poor intrinsic activity, low density of active sites or low electrical conductivity. Some are inert for electrocatalytic reactions, but are able to work as the functional substrates for hybrid electrocatalysts. Thus, tremendous strategies have been developed to modulate the physicochemical and electronic properties of 2D nanomaterial-based electrocatalysts, and to make full use of the functionalities of functional 2D nanomaterial substrates to achieve fast catalytic reaction kinetics. In this review, the recent progress on the well-established design strategies for the 2D nanomaterials-based electrocatalysts is highlighted. The perspectives on the current challenges and future development of 2D electrocatalysts are addressed.

Cobalt Sulfide Nanosheet/Graphene/Carbon Nanotube Nanocomposites as Flexible Electrodes for Hydrogen Evolution
Publisher: Wiley
Date: 08-10-2014
Abstract: Flexible three-dimensional (3D) nanoarchitectures have received tremendous interest recently because of their potential applications in wearable electronics, roll-up displays, and other devices. The design and fabrication of a flexible and robust electrode based on cobalt sulfide/reduced graphene oxide/carbon nanotube (CoS2 /RGO-CNT) nanocomposites are reported. An efficient hydrothermal process combined with vacuum filtration was used to synthesize such composite architecture, which was then embedded in a porous CNT network. This conductive and robust film is evaluated as electrocatalyst for the hydrogen evolution reaction. The synergistic effect of CoS2 , graphene, and CNTs leads to unique CoS2 /RGO-CNT nanoarchitectures, the HER activity of which is among the highest for non-noble metal electrocatalysts, showing 10 mA cm(-2) current density at about 142 mV overpotentials and a high electrochemical stability.

Unusual enhancement in electrical conductivity of tin oxide thin films with zinc doping
Publisher: Royal Society of Chemistry (RSC)
Date: 2011
DOI: 10.1039/C0CP00816H
Abstract: Electrical conductivity of SnO(2)-based oxides is of great importance for their application as transparent conducting oxides (TCO) and gas sensors. In this paper, for the first time, an unusual enhancement in electrical conductivity was observed for SnO(2) films upon zinc doping. Films with Zn/(Zn + Sn) reaching 0.48 were grown by pulsed spray-evaporation chemical vapor deposition. X-Ray diffraction (XRD) shows that pure and zinc-doped SnO(2) films grow in the tetragonal rutile-type structure. Within the low doping concentration range, Zn leads to a significant decrease of the crystallite size and electrical resistivity. Increasing Zn doping concentration above Zn/(Zn + Sn) = 0.12 leads to an XRD-amorphous film with electrical resistivity below 0.015 Ω cm at room temperature. Optical measurements show transparencies above 80% in the visible spectral range for all films, and doping was shown to be efficient for the band gap tuning.

One‐Pot Synthesis of Tunable Crystalline Ni3S4@Amorphous MoS2 Core/Shell Nanospheres for High‐Performance Supercapacitors
Publisher: Wiley
Date: 21-04-2015
Abstract: Transition metal sulfides gain much attention as electrode materials for supercapacitors due to their rich redox chemistry and high electrical conductivity. Designing hierarchical nanostructures is an efficient approach to fully utilize merits of each component. In this work, amorphous MoS(2) is firstly demonstrated to show specific capacitance 1.6 times as that of the crystalline counterpart. Then, crystalline core@amorphous shell (Ni(3)S(4)@MoS(2)) is prepared by a facile one-pot process. The diameter of the core and the thickness of the shell can be independently tuned. Taking advantages of flexible protection of amorphous shell and high capacitance of the conductive core, Ni(3)S(4) @amorphous MoS(2) nanospheres are tested as supercapacitor electrodes, which exhibit high specific capacitance of 1440.9 F g(-1) at 2 A g(-1) and a good capacitance retention of 90.7% after 3000 cycles at 10 A g(-1). This design of crystalline core@amorphous shell architecture may open up new strategies for synthesizing promising electrode materials for supercapacitors.

Publisher: Wiley
Date: 09-11-2018
Abstract: Developing clean and sustainable energies as alternatives to fossil fuels is in strong demand within modern society. The oxygen evolution reaction (OER) is the efficiency-limiting process in plenty of key renewable energy systems, such as electrochemical water splitting and rechargeable metal-air batteries. In this regard, ongoing efforts have been devoted to seeking high-performance electrocatalysts for enhanced energy conversion efficiency. Apart from traditional precious-metal-based catalysts, nickel-based compounds are the most promising earth-abundant OER catalysts, attracting ever-increasing interest due to high activity and stability. In this review, the recent progress on nickel-based oxide and (oxy)hydroxide composites for water oxidation catalysis in terms of materials design/synthesis and electrochemical performance is summarized. Some underlying mechanisms to profoundly understand the catalytic active sites are also highlighted. In addition, the future research trends and perspectives on the development of Ni-based OER electrocatalysts are discussed.
Hydrogen oxidation at the Pt–BaZr0.1Ce0.7Y0.1Yb0.1O3−δ (BZCYYb) interface
Publisher: Royal Society of Chemistry (RSC)
Date: 2013
DOI: 10.1039/C3CP44225J
Abstract: An asymmetric cell based on a proton conductor, BaZr(0.1)Ce(0.7)Y(0.1)Yb(0.1)O(3-δ) (BZCYYb), with a well-defined patterned Pt electrode was prepared to study the kinetics and mechanism of the hydrogen oxidation reaction under typical conditions for fuel cell operation and hydrogen separation, including operating temperature and hydrogen partial pressure. Steady-state polarization curves were carefully analyzed to determine the apparent exchange current density, limiting current density, and charge transfer coefficients. The empirical reaction order, as estimated from the dependence of electrode polarization (R(p)) and exchange current density on the partial pressure of hydrogen (P(H(2))), varied from 0.55 to 0.71. The results indicate that hydrogen dissociation contributes the most to the rate-limiting step of the hydrogen oxidation reaction taking place at the Pt-BZCYYb interface. At high current densities, surface diffusion of electroactive species appears to contribute to the rate-limiting step as well.

Publisher: IOP Publishing
Date: 12-05-2021
Abstract: The discovery of monolayered black phosphorus (phosphorene) in 2014 gives rise to enormous research enthusiasm for its unique electrical and physicochemical properties. Since then, the applications of black phosphorus and its nanostructures have been extended to various fields covering field effect transistors, rechargeable batteries, electrocatalysis, sensors, thermoelectric materials, and so forth.

In this review, we provide a state-of-the-art overview of the progress towards the synthesis of bulk BP and its typical nanostructured counterparts, including the 0D BP (quantum dots), 1D BP (nano/micro-belts), 2D BP (phosphorene), and 3D BP (sponges). Special focus will be made on the various synthetic methods, the characterizations of products, and the corresponding necessary improvements.

Enriched d‐Band Holes Enabling Fast Oxygen Evolution Kinetics on Atomic‐Layered Defect‐Rich Lithium Cobalt Oxide Nanosheets
Publisher: Wiley
Date: 14-04-2022
Abstract: Developing a reliable synthesis strategy to concurrently realize electronic structure modulation and two‐dimensionalization of materials is of paramount significance yet still challenging. Herein, a facile and universal strategy is reported to fabricate defect‐abundant atomic‐layered materials with unique electronic structures by mechanical shear‐assisted exfoliation. As a proof‐of‐concept demonstration, atomic‐layered defect‐rich LiCoO 2 nanosheets (AD‐LCO) are successfully synthesized, which enable accelerated oxygen evolution kinetics with a substantially decreased oxygen evolution reaction overpotential by 184 and 216 mV at 10 and 50 mA cm –2 , respectively. X‐ray absorption spectroscopy suggests that AD‐LCO possesses more d ‐band holes and enhanced Co‐O covalency. Density functional theory calculations reveal that the presence of Co lattice vacancies can optimize the adsorption kinetics of intermediates, consequently lowering the energy barrier of the rate‐determining step. Importantly, this method has universal applicability to the fabrication of other ultrathin defect‐rich 2D materials such as BN, WS 2 , and MoS 2 . The study has potential implications for offering novel insights into the rational design of ultrathin 2D materials with abundant surface defects for various applications.
Biochemistry-Enabled 3D Foams for Ultrafast Battery Cathodes
Publisher: American Chemical Society (ACS)
Date: 15-04-2015
Abstract: Metal vanadium phosphates (MVP), particularly Li3V2(PO4)3 (LVP) and Na3V2(PO4)3 (NVP), are regarded as the next-generation cathode materials in lithium/sodium ion batteries. These materials possess desirable properties such as high stability, theoretical capacity, and operating voltages. Yet, low electrical/ionic conductivities of LVP and NVP have limited their applications in demanding devices such as electric vehicles. In this work, a novel synthesis route for the preparation of LVP/NVP micro/mesoporous 3D foams via assembly of elastin-like polypeptides is demonstrated. The as-synthesized MVP 3D foams consist of microporous networks of mesoporous nanofibers, where the surfaces of in idual fibers are covered with MVP nanocrystallites. TEM images further reveal that LVP/NVP nanoparticles are about 100-200 nm in diameter, with each particle enveloped by a 5 nm thick carbon shell. The MVP 3D foams prepared in this work exhibit ultrafast rate capabilities (79 mA h g(-1) at 100C and 66 mA h g(-1) at 200C for LVP 3D foams 73 mA h g(-1) at 100C and 51 mA h g(-1) at 200C for NVP 3D foams) and excellent cycle performance (almost 100% performance retention after 1000 cycles at 100C) their properties are far superior compared to current state-of-the-art active materials.
Reversible Conversion-Alloying of Sb2O3 as a High-Capacity, High-Rate, and Durable Anode for Sodium Ion Batteries
Publisher: American Chemical Society (ACS)
Date: 31-10-2014
DOI: 10.1021/AM505505M
Abstract: Sodium ion batteries are attracting ever-increasing attention for the applications in large/grid scale energy storage systems. However, the research on novel Na-storage electrode materials is still in its infancy, and the cycling stability, specific capacity, and rate capability of the reported electrode materials cannot satisfy the demands of practical applications. Herein, a high performance Sb(2)O(3) anode electrochemically reacted via the reversible conversion-alloying mechanism is demonstrated for the first time. The Sb(2)O(3) anode exhibits a high capacity of 550 mAh g(-1) at 0.05 A g(-1) and 265 mAh g(-1) at 5 A g(-1). A reversible capacity of 414 mAh g(-1) at 0.5 A g(-1) is achieved after 200 stable cycles. The synergistic effect involving conversion and alloying reactions promotes stabilizing the structure of the active material and accelerating the kinetics of the reaction. The mechanism may offer a well-balanced approach for sodium storage to create high capacity and cycle-stable anode materials.

Toward Electrocatalytic Methanol Oxidation Reaction: Longstanding Debates and Emerging Catalysts
Publisher: Wiley
Date: 28-05-2023
Abstract: The study of direct methanol fuel cells (DMFCs) has lasted around 70 years, since the first investigation in the early 1950s. Though enormous effort has been devoted in this field, it is still far from commercialization. The methanol oxidation reaction (MOR), as a semi‐reaction of DMFCs, is the bottleneck reaction that restricts the overall performance of DMFCs. To date, there has been intense debate on the complex six‐electron reaction, but barely any reviews have systematically discussed this topic. To this end, the controversies and progress regarding the electrocatalytic mechanisms, performance evaluations as well as the design science toward MOR electrocatalysts are summarized. This review also provides a comprehensive introduction on the recent development of emerging MOR electrocatalysts with a focus on the innovation of the alloy, core–shell structure, heterostructure, and single‐atom catalysts. Finally, perspectives on the future outlook toward study of the mechanisms and design of electrocatalysts are provided.

DOI: 10.1021/ACS.NANOLETT.9B02729
Abstract: Rational hybridization of two-dimensional (2D) nanomaterials with extrinsic species has shown great promise for a wide range of applications. To date, rational design and engineering of heterostructures based on 2D metal-organic frameworks (MOFs) has been rather limited. Herein, we report an efficient strategy to construct noble metal/2D MOF heterostructures, featuring the utilization of surface oxygen sites from uncoordinated MOF ligands. The incorporation of highly dispersed noble metal nanoparticles (e.g., Pt and Pd) with modulated electronic structure is enabled on a surfactant-free MOF surface. As a proof-of-concept demonstration, the 2D Ni-MOF@Pt hybrid with well-defined interfaces is applied to boost the electrochemical hydrogen evolution reaction (HER) and delivers decent electrocatalytic activity under both acidic and alkaline conditions. The present results are expected to provide new insights into furnishing MOFs with extended functionalities and applications.

Strong Metal–Support Interaction in Heterogeneous Catalysts
Publisher: Wiley
Date: 07-08-2022
Abstract: Strong metal–support interaction (SMSI) in supported metal catalysts, typically accompanied by the formation of encapsulation layers over metal nanoparticles, has drawn intense research attention owing to a variety of intriguing behaviors. In particular, recent years have witnessed enormous progress in constructing SMSI between novel components as well as in understanding the nature of SMSI. Notably, SMSI also provides substantial possibilities for designing and modulating advanced heterogeneous catalysts toward a wide range of applications. Therefore, a systematic and critical overview is highly desirable to highlight the recent advances in SMSI and to discuss its applications in heterogeneous catalysts. In this review, the formation process of SMSI is described based on the typical material systems, and then the surface energy minimization mechanism is discussed by fully taking account of new material systems as well as novel construction strategies. Moreover, the principles of using SMSI to control the activity, selectivity, and stability of supported metal catalysts are demonstrated with an emphasis on thermocatalysis and electrocatalysis. To conclude, personal perspectives on the opportunities and challenges for SMSI are provided.

Evaluation of Aging and Health Status in Real Time Based on Routine Urinalysis Using an Automated Urine Analyzer
Publisher: Clinical Laboratory Publications
Date: 2015
DOI: 10.7754/CLIN.LAB.2015.150405
Abstract: To develop a quantitative system to enable straightforward objective assessment of health status in real time. On the basis of routine urinalysis with an automated urine analyzer, we obtained the urinalysis ill-health index (UIHI), which was the sum of urinary protein, pH, specific gravity, and color. Clinical laboratory parameters including stress indicators (neutrophilic leukocytes and glucose) and over-nutrition indicators (triglycerides, cholesterol, and uric acid) were monitored. The electrocardiography and blood pressure were also examined. A total of 1128 subjects were selected randomly from those who underwent physical examination to verify the UIHI. The range of the UIHI score was 0 to 5. The cutoff value was 2.75. There were correlations of UIHI score with laboratory parameters and abnormal rates of BP and ECG. A greater UIHI score reflected worse health status (p < 0.05). These data suggest that the UIHI can reflect the health status of an in idual. It can be derived easily from routine urinalysis in a clinical laboratory and may be a useful tool for the quantitative differentiation of health status in real time.
Two-Dimensional Tin Disulfide Nanosheets for Enhanced Sodium Storage
Publisher: American Chemical Society (ACS)
Date: 23-10-2015
Abstract: Sodium-ion batteries (SIBs) are considered as complementary alternatives to lithium-ion batteries for grid energy storage due to the abundance of sodium. However, low capacity, poor rate capability, and cycling stability of existing anodes significantly hinder the practical applications of SIBs. Herein, ultrathin two-dimensional SnS2 nanosheets (3-4 nm in thickness) are synthesized via a facile refluxing process toward enhanced sodium storage. The SnS2 nanosheets exhibit a high apparent diffusion coefficient of Na(+) and fast sodiation/desodiation reaction kinetics. In half-cells, the nanosheets deliver a high reversible capacity of 733 mAh g(-1) at 0.1 A g(-1), which still remains up to 435 mAh g(-1) at 2 A g(-1). The cell has a high capacity retention of 647 mA h g(-1) during the 50th cycle at 0.1 A g(-1), which is by far the best for SnS2, suggesting that nanosheet morphology is beneficial to improve cycling stability in addition to rate capability. The SnS2 nanosheets also show encouraging performance in a full cell with a Na3V2(PO4)3 cathode. In addition, the sodium storage mechanism is investigated by ex situ XRD coupled with high-resolution TEM. The high specific capacity, good rate capability, and cycling durability suggest that SnS2 nanosheets have great potential working as anodes for high-performance SIBs.
Enhanced Reaction Kinetics and Structure Integrity of Ni/SnO2 Nanocluster toward High-Performance Lithium Storage
Publisher: American Chemical Society (ACS)
Date: 20-11-2015
Abstract: SnO2 is regarded as one of the most promising anodes via conversion-alloying mechanism for advanced lithium ion batteries. However, the sluggish conversion reaction severely degrades the reversible capacity, Coulombic efficiency and rate capability. In this paper, through constructing porous Ni/SnO2 composite electrode composed of homogeneously distributed SnO2 and Ni nanoparticles, the reaction kinetics of SnO2 is greatly enhanced, leading to full conversion reaction, superior cycling stability and improved rate capability. The uniformly distributed Ni nanoparticles provide a fast charge transport pathway for electrochemical reactions, and restrict the direct contact and aggregation of SnO2 nanoparticles during cycling. In the meantime, the void space among the nanoclusters increases the contact area between the electrolyte and active materials, and accommodates the huge volume change during cycling as well. The Ni/SnO2 composite electrode possesses a high reversible capacity of 820.5 mAh g(-1) at 1 A g(-1) up to 100 cycles. More impressively, large capacity of 841.9, 806.6, and 770.7 mAh g(-1) can still be maintained at high current densities of 2, 5, and 10 A g(-1) respectively. The results demonstrate that Ni/SnO2 is a high-performance anode for advanced lithium-ion batteries with high specific capacity, excellent rate capability, and cycling stability.

Abstract: The coordination chemistry of the metal‐support interface largely determines the electrocatalytic performance of heterostructured electrocatalysts. However, it remains a great challenge to effectively manipulate the interface chemistry of heterostructures at the atomic level. Herein, functionalized carbon‐supported Ru heterostructured electrocatalysts are designed that contain abundant RuN(O)C moieties with a view towards fast hydrogen evolution reaction (HER). The coordination chemistry of the RuN(O)C moieties, and hence, the geometric and electronic structures of the Ru species can be precisely modulated via an appropriate annealing treatment. Specifically, the optimal heterostructured electrocatalyst delivers the highest specific activity by far among reported Ru‐based electrocatalysts, and the turnover frequency value reaches 32 s −1 at the overpotential (η) of 100 mV, which also surpasses the state‐of‐the‐art Pt/C catalyst in alkaline media. The interface engineering of the heterostructured electrocatalyst not only facilitates H 2 O adsorption and dissociation with help from the RuN(O)C moieties, but also further optimizes the adsorption behavior of H on the metallic Ru species, thereby inducing accelerated hydrogen evolution kinetics in both alkaline and acidic media. The present results demonstrate the successful atomic‐level interface engineering of carbon‐supported Ru‐based heterostructures and shed new light on the development of advanced electrocatalysts for fast hydrogen evolution, and beyond.

On the Durability of Iridium‐Based Electrocatalysts toward the Oxygen Evolution Reaction under Acid Environment
Publisher: Wiley
Date: 17-10-2021
Abstract: Proton exchange membrane water electrolyzers (PEMWEs) driven by renewable electricity provide a facile path toward green hydrogen production, which is critical for establishing a sustainable hydrogen society. The high working potential and the corrosive environment pose severe challenges for developing highly active and durable electrocatalysts for the oxygen evolution reaction (OER). To date, iridium (Ir)‐based materials, largely metallic Ir and Ir‐based oxides, are the most suitable OER electrocatalysts for PEMWEs due to their balanced activity and durability. Tremendous efforts have been devoted to improving the specific activity of Ir species to reduce the cost however, advances in enhancing the durability of Ir‐based electrocatalysts are rather limited. In this review, the recent research progress on tackling the stability issues of Ir‐based OER electrocatalysts in acid media is summarized, aiming to provide inspiration for designing highly active and stable Ir‐based electrocatalysts. The OER mechanism and the associated failure modes of active Ir species are summarized. Then, mechanistic studies on the dissolution behavior of Ir species and experimental attempts on enhancing the durability of Ir‐based electrocatalysts are discussed. The personal perspectives for future studies on Ir‐based OER electrocatalysts are also provided.

The impact of sodium aescinate on acute lung injury induced by oleic acid in rats
Publisher: Informa UK Limited
Date: 16-11-2011
DOI: 10.3109/01902148.2011.622426
Abstract: Acute lung injury (ALI) and acute respiratory distress syndrome (ARDS) are associated with high rates of morbidity and mortality. Currently, several surfactant or anti-inflammatory drugs are under test as treatments for ALI. Sodium aescinate (SA) has been shown to exert anti-inflammatory and antiedematous effects. In the present work, the authors explored the effects of SA and the possible mechanisms of SA action in rats with ALI induced by oleic acid (OA) administration. Eight groups of rats received infusions of normal saline (NS) or OA. Rats exposed to OA were pretreated with 1 mg/kg of SA, or posttreated with SA at low (1 mg/kg), medium (2 mg/kg), or high (6 mg/kg) dose a positive-control group received methylprednisolone. The pressure of oxygen in arterial blood (P(O(2))) levels, the pulmonary wet/dry weight (W/D) ratios, and indices of quantitative assessment (IQA) of histological lung injury were obtained 2 or 6 hours after OA injection (0.1 mL/kg, intravenously). The levels of superoxide dismutase (SOD), malondialdehyde (MDA), matrix metalloproteinase gelatinase B (MMP-9), and tissue inhibitor of metalloproteinase (TIMP-1) in both plasma and lung tissue were also determined. Both pre- and posttreatment with SA improved OA-induced pulmonary injury, increased P(O(2)) and SOD values, lowered IQA scores, and decreased the lung W/D ratio and MDA and MMP-9 levels in plasma and lung tissue. SA appeared to abrogate OA-induced ALI by modulating the levels of SOD, MDA, and MMP-9 in plasma and lung tissue.

Date: 11-12-2018
Abstract: Electrochemical water splitting is one of the potential approaches for making renewable energy production and storage viable. The oxygen evolution reaction (OER), as a sluggish four-electron electrochemical reaction, has to overcome high overpotential to accomplish overall water splitting. Therefore, developing low-cost and highly active OER catalysts is the key for achieving efficient and economical water electrolysis. In this work, Fe-doped NiMoO
Supported Sub‐Nanometer Clusters for Electrocatalysis Applications
Publisher: Wiley
Date: 12-04-2022
Abstract: Single‐atom catalysts (SACs) have attracted great attention in the field of electrocatalysis due to their exceptional activity, selectivity, 100% atom utilization, and tailorability of active sites at atomic level. The metal–support interactions and interatomic synergies, however, are severely limited due to the isolation of active sites in SACs which hinder their applications in some complex reactions. To this end, supported sub‐nanometer cluster catalysts (SNCCs, nm) with nearly fully exposed active atoms may outperform the SACs in some specific catalytic reactions. The presence of abundant chemical bonds in the clusters can flexibly regulate the support–cluster interaction and build ensemble effect in the sub‐nanometer clusters for different electrocatalysis applications. In this review, recent advances of supported SNCCs in electrocatalysis applications are summarized and discussed for the first time. In particular, the importance of the support–cluster interactions and ensemble effect of the clusters in determining the catalytic performance of SNCCs are highlighted. Lastly, challenges and opportunities in SNCCs electrocatalysis are prospected.
