Synthesis of nitrogen doped faceted titanium dioxide in pure brookite phase with enhanced visible light photoactivity
Publisher: Elsevier BV
Date: 05-2016
DOI: 10.1016/J.JCIS.2016.02.013
Abstract: Brookite titanium dioxide (TiO2) is rarely studied, as compared with anatase and rutile phases TiO2, due to its comparatively lower photoactivity. It has been recently reported that brookite TiO2 with active facets exhibits excellent performance, however, synthesis of such faceted brookite TiO2 is difficult because of its low thermodynamic phase stability and low structural symmetric. Furthermore, like faceted anatase and rutile TiO2, faceted brookite TiO2 is not responsive to visible light due to its wide bandgap. In this study, a novel dopant, hydrazine, was introduced in the development of nitrogen doping. By applying this dopant, nitrogen doped brookite nanorods with active {120}, {111} and {011¯} facets were successfully synthesized. The resultant materials exhibited remarkably enhanced visible-light photoactivity in photodegradation.

Boosting Electrocatalytic Activity of Single Atom Catalysts Supported on Nitrogen‐Doped Carbon through N Coordination Environment Engineering
Publisher: Wiley
Date: 13-01-2022
Abstract: Nonprecious group metal (NPGM)‐based single atom catalysts (SACs) hold a great potential in electrocatalysis and dopant engineering has been extensively exploited to boost their catalytic activity, while the coordination environment of dopant, which also significantly affects the electronic structure of SACs, and consequently their electrocatalytic performance, have been largely ignored. Here, by adopting a precursor modulation strategy, the authors successfully synthesize single cobalt atom catalysts embedded in nitrogen‐doped carbon, Co–N/C, with similar overall Co and N concentrations but different N types, that is, pyridinic N (N P ), graphitic N (N G ), and pyrrolic N (N PY ). Co–N/C with the Co–N 4 moieties coordinated with N G displays far superior activity for oxygen reduction (ORR) and evolution reactions, and superior activity and stability in both zinc–air batteries and proton exchange membrane fuel cells. Density functional theory calculation indicates that coordinated N species in particular N G functions as electron donors to the Co core of Co–N 4 active sites, leading to the downshift of d ‐band center of Co–N 4 and weakening the binding energies of the intermediates on Co–N 4 sites, thus, significantly promoting catalytic kinetics and thermodynamics for ORR in a full pH range condition.

DOI: 10.1007/S41918-022-00160-8
Abstract: Solid-state electrochemistry (SSE) is an interdisciplinary field bridging electrochemistry and solid-state ionics and deals primarily with the properties of solids that conduct ions in the case of ionic conducting solid electrolytes and electrons and/or electron holes in the case of mixed ionic and electronic conducting materials. However, in solid-state devices such as solid oxide fuel cells (SOFCs), there are unique electrochemical features due to the high operating temperature (600–1 000 °C) and solid electrolytes and electrodes. The solid-to-solid contact at the electrode/electrolyte interface is one of the most distinguished features of SOFCs and is one of the fundamental reasons for the occurance of most importance phenomena such as shift of the equipotential lines, the constriction effect, polarization-induced interface formation, etc. in SOFCs. The restriction in placing the reference electrode in solid electrolyte cells further complicates the SSE in SOFCs. In addition, the migration species at the solid electrode/electrolyte interface is oxygen ions, while in the case of the liquid electrolyte system, the migration species is electrons. The increased knowledge and understanding of SSE phenomena have guided the development of SOFC technologies in the last 30–40 years, but thus far, no up-to-date reviews on this important topic have appeared. The purpose of the current article is to review and update the progress and achievements in the SSE in SOFCs, largely based on the author’s past few decades of research and understanding in the field, and to serve as an introduction to the basics of the SSE in solid electrolyte devices such as SOFCs.

Atomically Dispersed Transition Metals on Carbon Nanotubes with UltraHigh Loading for Selective Electrochemical Carbon Dioxide Reduction
Publisher: Wiley
Date: 09-02-2018
Abstract: Single‐atom catalysts (SACs) are the smallest entities for catalytic reactions with projected high atomic efficiency, superior activity, and selectivity however, practical applications of SACs suffer from a very low metal loading of 1–2 wt%. Here, a class of SACs based on atomically dispersed transition metals on nitrogen‐doped carbon nanotubes (MSA‐N‐CNTs, where M = Ni, Co, NiCo, CoFe, and NiPt) is synthesized with an extraordinarily high metal loading, e.g., 20 wt% in the case of NiSA‐N‐CNTs, using a new multistep pyrolysis process. Among these materials, NiSA‐N‐CNTs show an excellent selectivity and activity for the electrochemical reduction of CO 2 to CO, achieving a turnover frequency (TOF) of 11.7 s −1 at −0.55 V (vs reversible hydrogen electrode (RHE)), two orders of magnitude higher than Ni nanoparticles supported on CNTs.

Advancement toward Polymer Electrolyte Membrane Fuel Cells at Elevated Temperatures
Publisher: American Association for the Advancement of Science (AAAS)
Date: 2020
Abstract: Elevation of operational temperatures of polymer electrolyte membrane fuel cells (PEMFCs) has been demonstrated with phosphoric acid-doped polybenzimidazole (PA/PBI) membranes. The technical perspective of the technology is simplified construction and operation with possible integration with, e.g., methanol reformers. Toward this target, significant efforts have been made to develop acid-base polymer membranes, inorganic proton conductors, and organic-inorganic composite materials. This report is devoted to updating the recent progress of the development particularly of acid-doped PBI, phosphate-based solid inorganic proton conductors, and their composite electrolytes. Long-term stability of PBI membranes has been well documented, however, at typical temperatures of 160°C. Inorganic proton-conducting materials, e.g., alkali metal dihydrogen phosphates, heteropolyacids, tetravalent metal pyrophosphates, and phosphosilicates, exhibit significant proton conductivity at temperatures of up to 300°C but have so far found limited applications in the form of thin films. Composite membranes of PBI and phosphates, particularly in situ formed phosphosilicates in the polymer matrix, showed exceptionally stable conductivity at temperatures well above 200°C. Fuel cell tests at up to 260°C are reported operational with good tolerance of up to 16% CO in hydrogen, fast kinetics for direct methanol oxidation, and feasibility of nonprecious metal catalysts. The prospect and future exploration of new proton conductors based on phosphate immobilization and fuel cell technologies at temperatures above 200°C are discussed.

A critical review of key materials and issues in solid oxide cells
Publisher: Wiley
Date: 2023
DOI: 10.1002/IDM2.12068
Abstract: Solid oxide cells (SOCs) are all solid ceramic devices with the dual functionality of solid oxide fuel cells (SOFCs) to convert the chemical energy of fuels like H 2 , natural gas and other hydrocarbons to electricity and of solid oxide electrolysis cells (SOECs) to store renewable electric energy of sun and wind in hydrogen fuel. Among the electrochemical energy conversion and storage devices, SOCs are the most clean and efficient technology with unique dual functionality. Due to the high operation temperature (typically 600–800°C), SOCs exhibit many advantages over other energy conversion devices, such as low material cost, high efficiency and fuel flexibility. There has been rapid development of SOC technologies over the last decade with significant advantages and progress in key materials and a fundamental understanding of key issues such as an electrode, electrolyte, performance degradation, poisoning, and stack design. The reversible polarization also has a critical effect on the surface segregation and stability of the electrode and electrode/electrolyte interface. This critical review starts with a brief introduction, working principles and thermodynamics of SOC technology to readers with interests in this rapidly developing and emerging field. Then the key materials currently used in SOCs are summarized, followed by the discussion of the most advanced electrode modification methods and critical issues of SOCs, including the surface chemistry, segregation, electrode/electrolyte interface and varying material degradation mechanisms under reversible operations. The challenges and prospects of SOC technology for future developments are discussed.

Photoelectrochemical N2‐to‐NH3 Fixation with High Efficiency and Rates via Optimized Si‐Based System at Positive Potential versus Li0/+
Publisher: Wiley
Date: 30-03-2023
Abstract: As a widely used commodity chemical, ammonia is critical for producing nitrogen‐containing fertilizers and serving as the promising zero‐carbon energy carrier. Photoelectrochemical nitrogen reduction reaction (PEC NRR) can provide a solar‐powered green and sustainable route for synthesis of ammonia (NH 3 ). Herein, an optimum PEC system is reported with an Si‐based hierarchically‐structured PdCu/TiO 2 /Si photocathode and well‐thought‐out trifluoroethanol as the proton source for lithium‐mediated PEC NRR, achieving a record high NH 3 yield of 43.09 µg cm −2 h −1 and an excellent faradaic efficiency of 46.15% under 0.12 MPa O 2 and 3.88 MPa N 2 at 0.07 V versus lithium(0/+) redox couple (vs Li 0/+ ). PEC measurements coupled with operando characterization reveal that the PdCu/TiO 2 /Si photocathode under N 2 pressures facilitate the reduction of N 2 to form lithium nitride (Li 3 N), which reacts with active protons to produce NH 3 while releasing the Li + to reinitiate the cycle of the PEC NRR. The Li‐mediated PEC NRR process is further enhanced by introducing small amount of O 2 or CO 2 under pressure by accelerating the decomposition of Li 3 N. For the first time, this work provides mechanistic understanding of the lithium‐mediated PEC NRR process and opens new avenues for efficient solar‐powered green conversion of N 2 ‐to‐NH 3 .

Identifying and tailoring C–N coupling site for efficient urea synthesis over diatomic Fe–Ni catalyst
Publisher: Springer Science and Business Media LLC
Date: 10-09-2022
DOI: 10.1038/S41467-022-33066-6
Abstract: Electrocatalytic urea synthesis emerged as the promising alternative of Haber–Bosch process and industrial urea synthetic protocol. Here, we report that a diatomic catalyst with bonded Fe–Ni pairs can significantly improve the efficiency of electrochemical urea synthesis. Compared with isolated diatomic and single-atom catalysts, the bonded Fe–Ni pairs act as the efficient sites for coordinated adsorption and activation of multiple reactants, enhancing the crucial C–N coupling thermodynamically and kinetically. The performance for urea synthesis up to an order of magnitude higher than those of single-atom and isolated diatomic electrocatalysts, a high urea yield rate of 20.2 mmol h −1 g −1 with corresponding Faradaic efficiency of 17.8% has been successfully achieved. A total Faradaic efficiency of about 100% for the formation of value-added urea, CO, and NH 3 was realized. This work presents an insight into synergistic catalysis towards sustainable urea synthesis via identifying and tailoring the atomic site configurations.

Surface Segregation in Solid Oxide Cell Oxygen Electrodes: Phenomena, Mitigation Strategies and Electrochemical Properties
Publisher: Springer Science and Business Media LLC
Date: 10-08-2020
DOI: 10.1007/S41918-020-00078-Z
Abstract: Solid oxide cells (SOCs) are highly efficient and environmentally benign devices that can be used to store renewable electrical energy in the form of fuels such as hydrogen in the solid oxide electrolysis cell mode and regenerate electrical power using stored fuels in the solid oxide fuel cell mode. Despite this, insufficient long-term durability over 5–10 years in terms of lifespan remains a critical issue in the development of reliable SOC technologies in which the surface segregation of cations, particularly strontium (Sr) on oxygen electrodes, plays a critical role in the surface chemistry of oxygen electrodes and is integral to the overall performance and durability of SOCs. Due to this, this review will provide a critical overview of the surface segregation phenomenon, including influential factors, driving forces, reactivity with volatile impurities such as chromium, boron, sulphur and carbon dioxide, interactions at electrode/electrolyte interfaces and influences on the electrochemical performance and stability of SOCs with an emphasis on Sr segregation in widely investigated (La,Sr)MnO 3 and (La,Sr)(Co,Fe)O 3− δ . In addition, this review will present strategies for the mitigation of Sr surface segregation.
Proton Transport in Hierarchical-Structured Nafion Membranes: A NMR Study
Publisher: American Chemical Society (ACS)
Date: 25-07-2017
DOI: 10.1021/ACS.JPCLETT.7B01557
Abstract: It is known that hierarchical structure plays a key role in many unique material properties such as self-cleaning effect of lotus leaves and the antifogging property of the compound eyes of mosquitoes. This study reports a series of highly ordered mesoporous Nafion membranes with unique hierarchical structural features at the nanometer scale. Using NMR, we show for the first time that, at low RH conditions, the proton in the ionic domains migrates via a surface diffusion mechanism and exhibits approximately 2 orders of magnitude faster transport than that in the nanopores, whereas the nanopores play a role of reservoir and maintain water and thereby conductivity at higher temperature and lower humidities. Thereby creating hierarchical nanoscale structures is a feasible and promising strategy to develop PEMs that would enable efficient electrochemical performance in devices such as fuel cells, even in the absence of high humidity and at elevated temperatures.

Development of In Situ Formed Metal Pyrophosphates (MP2O7, Where M = Sn, Ti, and Zr)/PA/PBI Based Composite Membranes for Fuel Cells
Publisher: Wiley
Date: 23-12-2022
Abstract: Development of high temperature polymer electrolyte membrane fuel cells (HT‐PEMFCs) at elevated temperatures is important for the enhancement of tolerance toward CO impurities and for the development of non‐precious metal catalysts. The key challenge in such HT‐PEMFCs is the high temperature polymer electrolyte membranes. Herein, the development of in situ formed metal pyrophosphates (MP 2 O 7 , where M = Sn, Ti, and Zr) in phosphoric acid doped polybenzimidazole (PA/PBI) composite membranes for HT‐PEMFCs is reported. The formation mechanism of MP 2 O 7 , and characteristics of MP 2 O 7 /PA/PBI composite membranes are studied in detail. In contrast to the rapid decay in performance of pristine PA/PBI membrane cells, the in situ formed MP 2 O 7 /PA/PBI composite membranes show significantly higher proton conductivity, improved performance, and stability at elevated temperatures of 200–250 °C. The best results are obtained on the in situ formed SnP 2 O 7 /PA/PBI composite membrane cells, exhibiting a high peak power density of 476 mW cm −2 and proton conductivity of 51.3 mS cm −1 at 250 °C. The excellent durability of SnP 2 O 7 /PA/PBI composite membrane is due to the uniform distribution of in situ formed SnP 2 O 7 nanoparticles in PBI membranes and the formation of a gel‐like region, thin and irregular amorphous layer on the SnP 2 O 7 with the high acid retention ability. This effectively alleviates the PA leaching at elevated temperatures of the new HT‐PEMFCs.

High‐Entropy Materials for Water Electrolysis
Publisher: Wiley
Date: 16-09-2022
Abstract: Green hydrogen production by renewables‐powered water electrolysis holds the key to energy sustainability and a carbon‐neutral future. The sluggish kinetics of water‐splitting reactions, namely, hydrogen evolution reaction (HER) and oxygen evolution reaction (OER), however, remains a bottleneck to the water electrolysis technology. High‐entropy materials, due to their compositional flexibility, structural stability, and synergy between various elemental components, have recently aroused considerable interest in catalyzing the water‐splitting reactions. Herein, a timely review of the recent achievements is provided in high‐entropy materials for water electrolysis. An overview of different kinds of high‐entropy materials for catalyzing the HER and OER half‐reactions is introduced, followed by a discussion of theoretical and experimental efforts in understanding the fundamental origins of the enhanced catalytic performance observed on high‐entropy catalysts. Various materials design strategies, including control of size and shape, construction of a porous structure, engineering of defect, and formation of hybrid/composite structure, to develop high‐entropy catalysts with improved catalytic performance are highlighted. Finally, the remaining challenges are pointed out and the corresponding perspectives to address these challenges are put forward to promote the development of the research field of high‐entropy water‐splitting catalysts.
