Highly Elastic Binders Incorporated with Helical Molecules to Improve the Electrochemical Stability of Black Phosphorous Anodes for Sodium-Ion Batteries
Publisher: Wiley
Date: 07-11-2020
Abstract: Black phosphorus has aroused attention as an attractive anode for sodium‐ion batteries, because of its high theoretical capacity. Nevertheless, its practical application is hindered by the large volume expansion, which results in rapid capacity decay. Herein, we report that this challenge can be addressed by using an elaborately designed binder for the phosphorus‐based electrodes. The incorporation of amylose molecules with helical structures endows the linear polyacrylic acid polymer binders with extraordinary stretchability and elasticity under 400 % strain. When it is applied as a binder for black‐phosphorus‐based anodes for sodium‐ion batteries, the adhesion between the electrode and the current collector is much stronger (2.95 N) than that of the polyvinylidene difluoride (PVDF) binder based one (1.90 N). The electrode delivered a capacity as high as 1280 mAh g −1 at 200 mA g −1 after 300 cycles, which is better than the electrode with PVDF binder. Impressively, even after 1000 cycles, the electrode with our binder exhibits a capacity retention of 80 %. Our work sheds light on the significance of the rational design of effective binders and provides a new strategy to further improve the electrochemical performance of phosphorus‐based materials for battery applications, which can be added on directly to other new electrode materials development strategies.

Boron-Doping Induced Electron Delocalization in Fluorophosphate Cathode: Enhanced Na-Ion Diffusivity and Sodium-Ion Full Cell Performance
Publisher: Wiley
Date: 24-05-2023
Abstract: Na 3 V 2 (PO 4 ) 2 O 2 F (NVPOF) is widely accepted as advanced cathode material for sodium‐ion batteries with high application prospects ascribing to its considerable specific capacity and high working voltage. However, challenges in the full realization of its theoretical potential lie in the novel structural design to accelerate its Na + diffusivity. Herein, considering the important role of polyanion groups in constituting Na + diffusion tunnels, boron (B) is doped at the P‐site to obtain Na 3 V 2 (P 2− x B x O 8 )O 2 F (NVP 2− x B x OF). As evidenced by density functional theory modeling, B‐doping induces a dramatic decrease in the bandgap. Delocalization of electrons on the O anions in BO 4 tetrahedra is observed in NVP 2− x B x OF, which dramatically lowers the electrostatic resistance experienced by Na + . As a result, the Na + diffusivity in the NVP 2− x B x OF cathode has accelerated up to 11 times higher, which secures a high rate property (67.2 mAh g −1 at 60 C) and long cycle stability (95.9% capacity retention at 108.6 mAh g −1 at 10 C after 1000 cycles). The assembled NVP 1.90 B 0.10 OF//Se‐C full cell demonstrates exceptional power/energy density (213.3 W kg −1 @ 426.4 Wh kg −1 and 17970 W kg −1 @ 119.8 Wh kg −1 ) and outstanding capability to withstand long cycles (90.1% capacity retention after 1000 cycles at 105.3 mAh g −1 at 10 C).

Sodium-rich NASICON-structured cathodes for boosting the energy density and lifespan of sodium-free-anode sodium metal batteries
Publisher: Wiley

DOI: 10.1002/INF2.12288
Abstract: Rechargeable sodium metal batteries (SMBs) have emerged as promising alternatives to commercial Li‐ion batteries because of the natural abundance and low cost of sodium resources. However, the overuse of metallic sodium in conventional SMBs limits their energy densities and leads to severe safety concerns. Herein, we propose a sodium‐free‐anode SMB (SFA‐SMB) configuration consisting of a sodium‐rich Na superionic conductor‐structured cathode and a bare Al/C current collector to address the above challenges. Sodiated Na 3 V 2 (PO 4 ) 3 in the form of Na 5 V 2 (PO 4 ) 3 was investigated as a cathode to provide a stable and controllable sodium source in the SFA‐SMB. It provides not only remarkable Coulombic efficiencies of Na plating/stripping cycles but also a highly reversible three‐electron redox reaction within 1.0–3.8 V versus Na/Na + confirmed by structural/electrochemical measurements. Consequently, an ultrahigh energy density of 400 Wh kg −1 was achieved for the SFA‐SMB with fast Na storage kinetics and impressive capacity retention of 93% after 130 cycles. A narrowed voltage window (3.0–3.8 V vs. Na/Na + ) further increased the lifespan to over 300 cycles with a high retained specific energy of 320 Wh kg −1 . Therefore, the proposed SFA‐SMB configuration opens a new avenue for fabricating next‐generation batteries with high energy densities and long lifetimes. image

Integrated Porous Cu Host Induced High-Stable Bidirectional Li Plating/Stripping Behavior for Practical Li Metal Batteries
Publisher: Wiley
Date: 02-12-2022
Abstract: The double‐sided electrodes with active materials are widely used for commercial lithium (Li) ion batteries with a higher energy density. Accordingly, developing an anode current collector that can accommodate the stable and homogeneous Li plating/stripping on both sides will be highly desired for practical Li metal batteries (LMBs). Herein, an integrated bidirectional porous Cu (IBP‐Cu) film with a through‐pore structure is fabricated as Li metal hosts using the powder sintering method. The resultant IBP‐Cu current collector with tunable pore volume and size exhibits high mechanical flexibility and stability. The bidirectional and through‐pore structure enables the IBP‐Cu host to achieve homogeneous Li deposition and effectively suppresses the dendritic Li growth. Impressively, the as‐fabricated Li/IBP‐Cu anode exhibits a remarkable capacity of up to 7.0 mAh cm −2 for deep plating/stripping, outstanding rate performance, and ultralong cycling ability with high Coulombic efficiency of ≈100% for 1000 cycles. More practicably, a designed pouch cell coupled with one Li/IBP‐Cu anode and two LiFePO 4 cathodes exhibits a highly elevated energy density (≈187.5%) compared with a pouch cell with one anode and one cathode. Such design of a bidirectional porous Cu current collector with stable Li plating/stripping behaviors suggests its promising practical applications for next‐generation Li metal batteries.
Effects of graphene oxide on the development of offspring mice in lactation period
Publisher: Elsevier BV

DOI: 10.1016/J.BIOMATERIALS.2014.11.014
Abstract: The potential toxicity of graphene oxide (GO) has attracted much attention with numerous promising biomedical applications in recent years. However, information about GO on the development of filial animals is rare. In this work, we studied the potential developmental toxicity of GO when they entered the body of maternal mice and their offspring by oral exposure with two doses. The results showed that the increase of body weight, body length and tail length of the filial mice received GO at 0.5 mg mL(-1) (about 0.8 mg each mouse) every day in the lactation period was significantly retarded comparing with the control group. The anatomy and histology results revealed the delayed developments of offspring in high dosage group. We also evaluated the possible toxicological mechanism caused by GO and found that the length of the intestinal villus of the filial mice received high concentration GO were decreased significantly compared with the control group. It can be concluded that GO showed many negative effects on the development of mice in the lactation period. These findings can be significant for the development of graphene materials-based drug delivery system and other biomedical applications in the future.

Enhanced photocatalytic activity and structural stability by hybridizing Ag3 PO4 nanospheres with graphene oxide sheets
Publisher: Royal Society of Chemistry (RSC)
Date: 2012
DOI: 10.1039/C2CP42465G
Abstract: Graphene oxide (GO)-Ag(3)PO(4) nanocomposites synthesized through a facile solution approach via electrostatic interaction were investigated as excellent photocatalysts for the degradation of rhodamine B (RhB) under visible light irradiation. SEM and TEM observations indicate that Ag(3)PO(4) nanospheres of ~120 nm in diameter were well dispersed and anchored onto the exfoliated GO sheets. The characterizations of FTIR and Raman demonstrated the existence of strong charge interactions between GO sheets and Ag(3)PO(4) nanospheres. As compared to Ag(3)PO(4) nanospheres alone, the attachments of GO sheets led to a band gap narrowing (2.10 eV) and a strong absorbance in the near infrared region (NIR). The photoluminescence (PL) analysis indicates a more efficient separation of electron-hole pairs in the GO-Ag(3)PO(4) nanocomposites. Notably, the incorporation of GO sheets not only significantly enhances the photocatalytic activity but also improves the structural stability of Ag(3)PO(4). The positive synergistic effects between Ag(3)PO(4) nanospheres and GO sheets are proposed to contribute to the improved photocatalytic properties. A possible photocatalytic mechanism of the GO-Ag(3)PO(4) nanocomposites was assumed as well. The integration of these advantages enables such GO-Ag(3)PO(4) hybrid material to be a nice photocatalyst for broad applications in a sewage treatment system.
Ultrasonic Spray Pyrolysis‐assisted Fabrication of Ultrathin CuWO4 Films with Improved Photoelectrochemical Performance
Publisher: Wiley
Date: 04-12-2021
Abstract: CuWO 4 is a promising n‐type oxide semiconductor for photoelectrochemical (PEC) applications due to the suitable band gap and good photochemical stability. An easy and large‐scale fabrication of ultrathin CuWO 4 films with improved PEC performance is highly desired for future practical application but still challenging. Considering that the ultrasonic spray pyrolysis approach is a low‐cost and scalable technique for fabricating films with controllable thickness, we here report the controllable fabrication of ultrathin CuWO 4 films with improved PEC performance by an automatic ultrasonic spray pyrolysis method. The effects of different tungsten sources and film thickness on the PEC performance of the resultant CuWO 4 film were studied in detail. We find that the ultrathin CuWO 4 film prepared from the ammonium metatungstate with a thickness of 2.16 μm shows the best PEC performance of 41 μA cm −2 at 1.23 V vs.RHE for water oxidation under visible light irradiation. We also explored the different charge transfer mechanism and PEC performance of the resultant CuWO 4 films under back and front illumination.
Localized Electron Density Redistribution in Fluorophosphate Cathode: Dangling Anion Regulation and Enhanced Na-Ion Diffusivity for Sodium-Ion Batteries
Publisher: Wiley
Date: 10-11-2022
Abstract: Polyanionic transition metal polyphosphate (TMPO)‐type Na 3 V 2 (PO 4 ) 2 O 2 F (NVPO 2 F) is promising as cathode for large‐scale sodium‐ion batteries (SIBs) on account of its considerable capacity and highly stable structure. However, the redox of transition metal and phase transitions along with the (de)intercalation of Na + lead to its slow kinetics and inferior rate performance. Herein, chlorine (Cl) is applied as a heteropical dopant to obtain Cl‐doped NVPO 2 F (NVPO 2−x Cl x F) cathode material for SIBs. Density functional theory investigation reveals that Cl doping tunes the localized electronic density and structure in NVPO 2 F lattice, causing the electron redistribution on vanadium center and dangling anions. Hence, the NVPO 2−x Cl x F cathode exhibits a revised redox behavior of vanadium for Na + extraction/insertion, increases Na + diffusion rate, as well as lowers charge transfer resistance. A Na + storage mechanism of reversible transformations between three phases and V 4+ /V 5+ redox couple for NVPO 2−x Cl x F cathode is verified. The NVPO 2−x Cl x F cathode reveals a high rate capacity of ≈63 mAh g −1 at 30C and great cycle stability over 1000 cycles at 10C. More importantly, outstanding rate property (314 Wh kg −1 at 5850 W kg −1 ) and cycling capability are obtained for the NVPO 2−x Cl x F//3DC@Se full cell. This study demonstrates a brand‐new strategy to prepare advanced cathode materials for superior SIBs.

A Composite Polymeric Carbon Nitride with In Situ Formed Isotype Heterojunctions for Highly Improved Photocatalysis under Visible Light
Publisher: Wiley
Date: 09-12-2017
Abstract: Introducing heterojunction is an effective way for improving the intrinsic photocatalytic activity of a graphitic carbon nitride (GCN) semiconductor. These heterostructures are mostly introduced by interfacing GCN with foreign materials that normally have entirely different physicochemical properties and show unfavorable compatibility, thus resulting in a limited improvement of the photocatalytic performance of the resultant materials. Herein, a composite polymeric carbon nitride (CPCN) that contains both melon-based GCN and triazine-based crystalline carbon nitride (CCN) is prepared by a simple thermal reaction between lithium chloride and GCN. Thanks to the intimate contact and good compatibility between GCN and CCN, an in situ formed heterojunction acts as a driving force for separating the photogenerated charge carriers in CPCN. As a result, CPCN exhibits a significantly improved photocatalytic performance under visible light irradiation, which is, respectively, 10.6 and 5.3 times as high as those of the GCN and CCN alone. This well designed isotype heterojunction by a coupling of CCN presents an effective avenue for developing efficient GCN photocatalysts.

Deeply Cyclable and Ultrahigh-Rate Lithium Metal Anodes Enabled by Coaxial Nanochamber Heterojunction on Carbon Nanofibers
Publisher: Wiley
Date: 23-10-2021
Abstract: Lithium metal anodes (LMAs) are the most promising candidates for high‐energy‐density batteries due to the high theoretical specific capacity and lowest potential. However, the practical application of LMAs is h ered by the short lifespan and unsatisfactory lithium utilization ( %). An oxide–oxide heterojunction enhanced with nanochamber structure design is proposed to improve lithium utilization and cycling performance of LMA under ultrahigh rates. Typically, a MnO 2 –ZnO heterojunction provides high binding energy for strong absorption of Li‐ions and intimately bonded interfaces for fast transfer of electrons. Under the guidance of the smooth Li‐ion migration and rapid electron flow, the Li metal can be restricted as thin layers within submicro scale in nanochambers with constrain boundary and stress dissipation, inhibiting the local agglomeration and blocking. Thus, the lithiophilic active sites can be effectively exposed to the Li‐ions within submicro scale, improving the reversible conversion for high lithium utilization during long‐term cycling. As such, the Li@MnZnO/CNF electrode achieves a high lithium utilization of 70% at a record‐high current density of 50 mA cm −2 with areal capacity of 10 mAh cm −2 . This work offers an avenue to improve lithium utilization for long‐lifespan LMAs working under high current densities and capacities.

Harnessing the 2D Structure-Enabled Viscoelasticity of Graphene-Based Hydrogel Membranes for Chronic Neural Interfacing
Publisher: Wiley
Date: 08-03-2022
Abstract: Stiffness and viscoelasticity of neural implants regulate the foreign body response. Recent studies have suggested the use of elastic or viscoelastic materials with tissue‐like stiffness for long‐term neural electrical interfacing. Herein, the authors find that a viscoelastic multilayered graphene hydrogel (MGH) membrane, despite exhibiting a much higher Young's modulus than nerve tissues, shows little inflammatory response after 8‐week implantation in rat sciatic nerves. The MGH membrane shows significant viscoelasticity due to the slippage between graphene nanosheets, facilitating its seamless yet minimally compressive interfacing with nerves to reduce the inflammation caused by the stiffness mismatch. When used as neural stimulation electrodes, the MGH membrane can offer abundant ion‐accessible surfaces to bring a charge injection capacity 1–2 orders of magnitude higher than its traditional Pt counterpart, and further demonstrates chronic neural therapy potential in low‐voltage modulation of rat blood pressure. This work suggests that the emergence of 2D nanomaterials and particularly their unique structural attributes can be harnessed to enable new bio‐interfacing design strategies.
New engineering science insights into the electrodes pairing of electrochemical energy storage devices assisted by machine learning
Publisher: Research Square Platform LLC
Date: 18-05-2022
DOI: 10.21203/RS.3.RS-831006/V1
Abstract: Pairing the positive and negative electrodes with their in idual dynamic characteristics properly matched is essential to the optimal design of electrochemical energy storage devices. However, the complex relationship between the performance data measured for in idual electrodes and the two-electrode cells used in practice often makes an optimal pairing experimentally challenging. In this work, taking graphene-based supercapacitors as an ex le, we combine experiments with machine learning to generate a large pool of capacitance data for graphene-based electrode materials with varied slit pore sizes and thicknesses, and numerically pair them into different combinations for two-electrode cells. The as-achieved pairing results allow us to conduct a comprehensive analysis of the correlations between the key electrode structural features of in idual electrodes and volumetric capacitance of the resultant two-electrode cells. The results show that the optimal pairing parameters are varied considerably with the operation rate of the cells and are even influenced by the thickness of the inactive components. The best-performing in idual electrode does not necessarily result in optimal cell-level performance. The machine learning-assisted pairing approach presents much higher efficiency compared with the traditional trial-and-error approach for the optimal design of supercapacitors and provides an additional effective avenue for further improving the performance of supercapacitors and is expected to play an enabling role in the future on-demand design of energy storage devices. The results observed in this work also indicate the call for comprehensive performance data reporting in the electrochemical energy storage field to enable the adoption of artificial intelligence techniques to accelerate the translation of academic research in this rapidly growing field.

A Self-Regulated Interface toward Highly Reversible Aqueous Zinc Batteries
Publisher: Wiley
Date: 15-01-2022
Abstract: Aqueous zinc batteries, that demonstrate high safety and low cost, are considered promising candidates for large‐scale energy storage. However, Zn anodes suffer from rapid performance deterioration due to the severe Zn dendrite growth and side reactions. Herein, with a low‐cost ammonium acetate (NH 4 OAc) additive, a self‐regulated Zn/electrolyte interface is built to address these problems. The NH 4 + induces a dynamic electrostatic shielding layer around the abrupt Zn protuberance to make the Zn deposition uniform, and the OAc − acts as an interfacial pH buffer to suppress the proton‐induced side reactions and the precipitation of insoluble by‐products. As a result, in the electrolyte with the NH 4 OAc additive, Zn anodes exhibit a long cycling stability of 3500 h at 1 mA cm −2 , an impressive cumulative areal capacity of 5000 mAh cm −2 at 10 mA cm −2 , and a high Coulombic efficiency of ≈ 99.7%. A prototype full cell coupled with a NH 4 V 4 O 10 cathode performs much better in terms of capacity retention than the additive‐free case. The findings pave the way for developing practical Zn batteries.

Designing Advanced Liquid Electrolytes for Alkali Metal Batteries: Principles, Progress, and Perspectives
Publisher: Wiley
Date: 22-04-2023
DOI: 10.1002/EEM2.12355
Abstract: The ever‐growing pursuit of high energy density batteries has triggered extensive efforts toward developing alkali metal (Li, Na, and K) battery (AMB) technologies owing to high theoretical capacities and low redox potentials of metallic anodes. Typically, for new battery systems, the electrolyte design is critical for realizing the battery electrochemistry of AMBs. Conventional electrolytes in alkali ion batteries are generally unsuitable for sustaining the stability owing to the hyper‐reactivity and dendritic growth of alkali metals. In this review, we begin with the fundamentals of AMB electrolytes. Recent advancements in concentrated and fluorinated electrolytes, as well as functional electrolyte additives for boosting the stability of Li metal batteries, are summarized and discussed with a special focus on structure–composition–performance relationships. We then delve into the electrolyte formulations for Na‐ and K metal batteries, including those in which Na/K do not adhere to the Li‐inherited paradigms. Finally, the challenges and the future research needs in advanced electrolytes for AMB are highlighted. This comprehensive review sheds light on the principles for the rational design of promising electrolytes and offers new inspirations for developing stable AMBs with high performance.
Engineering current collectors for advanced alkali metal anodes: A review and perspective
Publisher: Wiley
Date: 29-08-2023
DOI: 10.1002/EOM2.12269
Abstract: Alkali metal batteries (AMBs) are promising next‐generation high‐density electrochemical energy storage systems. In addition, current collectors play important roles in enhancing their electrochemical performances. Thus, it is essential to have a critical review of the most recent advances in engineering the current collectors for high‐performance AMBs. In this review paper, the fundamentals of alkali metal deposition on current collectors will be introduced first. Then recent advances in the development of advanced metal and carbon‐based current collectors are examined for boosting the stability and cycle life of lithium metal batteries (LMBs) in terms of various strategies including 3D architectural design and functional modifications. Thereafter, the research progress in design of advanced current collectors will be analyzed for sodium otassium metal batteries, especially the counterparts that do not follow the paradigms established in LMBs. Finally, the major challenges and key perspectives will be discussed for the future development of current collectors in AMBs. image
Probing Nanoconfined Ion Transport in Electrified 2D Laminate Membranes with Electrochemical Impedance Spectroscopy
Publisher: Wiley
Date: 23-09-2022
Abstract: The recent emergence of electrically conductive nanoporous membranes based on graphene and other 2D materials opens up new opportunities to revisit some longstanding nanoconfined ion transport problems under electrification. This work probes the ionic resistance in electrified multilayered graphene membranes with electrochemical impedance spectroscopy. This study demonstrates that the combination of additive‐free feature and tunable slit pore sizes in the sub‐10 nm range in graphene‐based membranes has made it possible to deconvolute the different ionic processes from the impedance obtained and examine the exclusive influence of pore size on the ionic resistance in a quantitative manner. The trends revealed for the ionic resistance at the pore entrance and inside the pores under severe nanoconfinement ( nm) are found to be generally consistent with the microscale theoretical simulations previously reported. It also allows a quantitative analysis of the relative effects of the external polarization potential and ion identity under nanoconfinement. The results suggest that the classic electrochemical impedance spectroscopy technique, when applied to appropriate nanoporous electrode materials, can provide rich information about nanoconfined ion transport phenomena under electrification for fundamental understanding and application development.

DOI: 10.1098/RSOS.180187
Abstract: The key to solving environmental and energy issues through photocatalytic technology requires highly efficient, stable and eco-friendly photocatalysts. Graphitic carbon nitride (g-C 3 N 4 ) is one of the most promising candidates except for its limited photoactivity. In this work, a facile and scalable one-step method is developed to fabricate an efficient heterostructural g-C 3 N 4 photocatalyst in situ coupled with MoS 2 . The strong coupling effect between the MoS 2 nanosheets and g-C 3 N 4 scaffold, numerous mesopores and enlarged specific surface area helped form an effective heterojunction. As such, the photocatalytic activity of the g-C 3 N 4 /MoS 2 is more than three times higher than that of the pure g-C 3 N 4 in the degradation of RhB under visible light irradiation. Improvement of g-C 3 N 4 /MoS 2 photocatalytic performance is mainly ascribed to the effective suppression of the recombination of charge carriers.
A honeycomb-like porous carbon derived from pomelo peel for use in high-performance supercapacitors
Publisher: Royal Society of Chemistry (RSC)
Date: 16-02-0010
DOI: 10.1039/C4NR04541F
Abstract: A cost-effective approach to obtain electrode materials with excellent electrochemical performance is critical to the development of supercapacitors (SCs). Here we report the preparation of a three-dimensional (3D) honeycomb-like porous carbon (HLPC) by the simple carbonization of pomelo peel followed by KOH activation. Structural characterization indicates that the as-prepared HLPC with a high specific surface area (SSA) up to 2725 m(2) g(-1) is made up of interconnected microporous carbon walls. Chemical analysis shows that the HLPC is doped with nitrogen and also has oxygen-containing groups. Electrochemical measurements show that the HLPC not only exhibits a high specific capacitance of 342 F g(-1) and 171 F cm(-3) at 0.2 A g(-1) but also shows considerable rate capability with a retention of 62% at 20 A g(-1) as well as good cycling performance with 98% retention over 1000 cycles at 10 A g(-1) in 6 M KOH. Furthermore, an as-fabricated HLPC-based symmetric SC device delivers a maximum energy density of ∼9.4 Wh kg(-1) in the KOH electrolyte. Moreover, the outstanding cycling stability (only 2% capacitance decay over 1000 cycles at 5 A g(-1)) of the SC device makes it promising for use in a high-performance electrochemical energy system.

Material Design and Energy Storage Mechanism of Mn-Based Cathodes for Aqueous Zinc-Ion Batteries
Publisher: Wiley
Date: 20-09-2022
Abstract: Mn‐based cathodes have been widely explored for aqueous zinc‐ion batteries (ZIBs), by virtue of their high theoretical capacity and low cost. However, Mn‐based cathodes suffer from poor rate capability and cycling performance. Researchers have presented various approaches to address these issues. Therefore, these endeavors scattered in various directions ( e. g ., designing electrode structures, defect engineering and optimizing electrolytes) are necessary to be connected through a systematic review. Hence, we comprehensively overview Mn‐based cathode materials for ZIBs from the aspects of phase compositions, electrochemical behaviors and energy storage mechanisms, and try to build internal relations between these factors. Modification strategies of Mn‐based cathodes are then introduced. Furthermore, this review also provides some new perspectives on future efforts toward high‐energy and long‐life Mn‐based cathodes for ZIBs.

Synergy of Nb Doping and Surface Alloy Enhanced on Water–Alkali Electrocatalytic Hydrogen Generation Performance in Ti-Based MXene
Publisher: Wiley
Date: 05-04-2019
Abstract: Presented are the theoretical calculation and experimental studies of a Ti 3 C 2 T x MXene‐based nanohybrid with simultaneous Nb doping and surface transition metal alloy modification. Guided by the density functional theory calculation, the Nb doping can move up the Fermi energy level to the conduction band, thus enhancing the electronic conductivity. Meanwhile, the surface modification by Ni/Co alloy can moderate the surface M–H affinity, which will further enhance the hydrogen evolution reaction (HER) activity. A series of Ni/Co alloy attached on Nb‐doped Ti 3 C 2 T x MXene nanohybrids (denoted as NiCo@NTM) are successfully prepared. As expected, the Ni 0.9 Co 0.1 @ NTM nanohybrids present an extraordinary HER activity in alkaline solution, which only needs an overpotential (η) of 43.4 mV to reach the current density of 10 mA cm −2 in 1 m KOH solution and shows good stability. The performance of the Ni 0.9 Co 0.1 @ NTM nanohybrids is comparable to the commercial 10% Pt/C electrode (34.4 mV@10 mA cm −2 ) and is better than most state‐of‐the‐art Pt‐free HER catalysts. Inspired by the facile synthesis process and chemical versatility of both MXene and transition metal alloys, the nanohybrids reported here are promising non‐noble metal electrocatalysts for water–alkali electrolysis.
