Electrochemical water splitting for hydrogen generation is considered one of the most promising strategies for reducing the use of fossil fuels and storing renewable electricity in hydrogen fuel.However,the anodic oxygen evolution process remains a bottleneck due to the remarkably high overpotential of about 300 mV to achieve a current density of 10 mA cm^(−2).The key to solving this dilemma is the development of highly efficient catalysts with minimized overpotential,long-term stability,and low cost.As a new 2D material,MXene has emerged as an intriguing material for future energy conversion technology due to its benefits,including superior conductivity,excellent hydrophilic properties,high surface area,versatile chemical composition,and ease of processing,which make it a potential constituent of the oxygen evolution catalyst layer.This review aims to summarize and discuss the recent development of oxygen evolution catalysts using MXene as a component,emphasizing the synthesis and synergistic effect of MXene-based composite catalysts.Based on the discussions summarized in this review,we also provide future research directions regarding electronic interaction,stability,and structural evolution of MXene-based oxygen evolution catalysts.We believe that a broader and deeper research in this area could accelerate the discovery of efficient catalysts for electrochemical oxygen evolution.

Industrial water splitting has long been suppressed by the sluggish kinetics of the oxygen evolution reaction(OER),which requires a catalyst to be efficient.Herein,we propose a molecular-level proton acceptor strategy to produce an efficient OER catalyst that can boost industrial-scale water splitting.Molecular-level phosphate(-PO_(4))group is introduced to modify the surface of PrBa_(0.5)Ca_(0.5)Co_(2)O_(5)+δ(PBCC).The achieved catalyst(PO_(4)-PBCC)exhibits significantly enhanced catalytic performance in alkaline media.Based on the X-ray absorption spectroscopy results and density functional theory(DFT)calculations,the PO_(4)on the surface,which is regarded as the Lewis base,is the key factor to overcome the kinetic limitation of the proton transfer process during the OER.The use of the catalyst in a membrane electrode assembly(MEA)is further evaluated for industrial-scale water splitting,and it only needs a low voltage of 1.66 V to achieve a large current density of 1 A cm^(-2).This work provides a new molecular-level strategy to develop highly efficient OER electrocatalysts for industrial applications.

oxygen defects play a critical role in the electrocatalytic oxygen evolution reaction(OER).Therefore,in-depth understanding the structure-activity-mechanism relationship of these defects is the key to design efficient OER electrocatalysts.This relationship needs to be understood dynamically due to the potential for irreversible phase transitions during OER.Consequently,significant efforts have been devoted to study the dynamic evolution of oxygen defects to shed light on the OER mechanism.This review critically examines and analyzes the dynamic processes occurring at oxygen defect sites during OER,including defect formation and defect evolution mechanisms,along with the advanced characterization techniques needed to understand these processes.This review aims to provide a comprehensive understanding of high-efficiency electrocatalysts,with a particular emphasis on the importance of in situ monitoring the dynamic evolution of oxygen defects,providing a new perspective towards efficient OER electrocatalyst design.

Transition metal phosphides have been recognized as promising electrocatalysts for oxygen evolution reaction(OER) due to their low cost and high activity. However, the insufficient exposed active region limited the OER performance. Recently, the introduction of sacrificial dopants has been considered an effective strategy to enlarge the surface area. Herein, the Zn dopants are introduced in NiFe phosphide(NiFeZnP) nanosheet, which work as the sacrificial dopants to generate more exposed active NiFe sites and promote the formation of the NiFeOOH active phase during OER process. The optimized Zn-doped NiFeP catalyst shows an overpotential of ≈203 mV to reach a current density of 10 mA cm-2in 1 M KOH, and a stability of 100 h at 1000 mA cm-2. Overall, this work provides a sacrificial Zn doping strategy to prepare highly efficient OER electrocatalysts.

oxygen evolution reaction（OER） catalysts are the key core materials that determine the performance of fuel cells,metal-air batteries,electrolytic water decomposition,and other applications.In this work,a green lignin-based non-precious metal OER catalyst was prepared by a simple strategy.Firstly,c arboxylated lignin was used to complex Ni and Co in situ,and then they were placed with sodium hypophosphite in the same tube furnace for upstream and downstream high-temperature calcination to construct a lignin carbon-based Ni-Co bimetallic OER catalyst（NiCoP@C）.The synthesized catalyst is a porous bimetallic phosphide with a three-dimensional network structure and high-density electrochemical active sites.NiCoP@C exhibited favorable catalytic activity for the oxygen evolution reaction（OER） with overpotential of 280 mV at 10 mA·cm-2and a Tafel slope of 77 mV·dec-1.Additionally,it exhibited remarkable durability during usage.Density functional theory（DFT） calculations revealed that by leveraging the distinctive structure of transition metal phosphide nanoparticles incorporated into a reticulated substrate,the NiCoP@C catalyst offered an increased number of active sites for OER catalysis,significantly enhancing its stability during practical applications.The present study broadens the utilization pathways of biomass to "turn waste into treasure," aligning the development concept of green sustainable development.

Catalysts consisting of Zeolite imidazolyl ester skeleton-67(ZIF-67)and graphene oxide(GO)were fabricated through a solvothermal method,followed by etching ZIF-67 with oxygen-rich functional groups on GO in a reduction atmosphere at 400℃.During this process,an open type of cobalt metal center was formed by the partial vaporization and oxidation of ZIF-67,further reducing to Co and partially combining with oxygen species to amorphous CoOx.Benefiting from the rich functional N,and metal/oxides active centers derived from the calcination process,the synthesized Co/CoOx@NSG-400 showed a low OER overpotential of 10 mA·cm^(-2) at 298 mV,and an ORR half-wave potential of 0.8 V,which demonstrated its excellent bifunctional catalytic activity.Such a controllable calcination strategy with high yields could be expected to pave the way for synthesizing low-cost and efficient bifunctional electrocatalysts.

Developing high-performance and low-cost electrocatalysts for oxygen evolution reaction(OER)is still a great challenge for water-splitting technologies.Herein,an innovative metal-organic frameworks(MOFs)hybrid-assisted strategy is reported to synthesize core-shell Co/Mn-ZIF@Fe-Co-Mn Prussian blue analogues(PBAs)toward highly efficient OER electrocatalysts in alkaline electrolyte.Physical characterization indicates that the amorphous hydroxide transformed from Co/Mn-ZIF@Fe-Co-Mn PBA(ZIF:zeolitic imidazolate frameworks)during the electrochemical process acted as the electroactive species.Benefiting from these structural and compositional features,the developed composite delivers a remarkably low overpotential of 270 mV with a current density of 10 mA·cm^(−2)in 1.0 M KOH solution.Moreover,water splitting is catalyzed to reach a current density of 10 mA·cm^(−2)at 1.62 V.

Alkaline water electrolysis provides a promising route for"green hydrogen"generation,where anodic oxygen evolution reaction(OER)plays a crucial role in coupling with cathodic hydrogen evolution reaction.To date,the development of highly active and durable OER catalysts based on earth-abundant elements has drawn wide attention;nevertheless,their performance under high current densities(HCDs≥1000 mA cm^(-2))has been less emphasized.This situation has seriously impeded large-scale electrolysis industrialization.In this review,in order to provide a guideline for designing high-performance OER electrocatalysts,the effects of HCD on catalytic performance involving electron transfer,mass transfer,and physical/chemical stability are summarized.Furthermore,the design principles were pointed out for obtaining efficient and robust OER electrocatalysts in light of recent progress of OER electrocatalysts working above 1000 mA cm^(-2).These include the aspects of developing self-supported catalytic electrodes,enhancing intrinsic activity,enhancing the catalyst-support interaction,engineering surface wettability,and introducing protective layer.Finally,summaries and outlooks in achieving OER at industrially relevant HCDs are proposed.

Dual elemental modulation in cationic and anionic sites of the multi-metal Prussian blue analogue pre-catalysts for promoted oxygen evolution reaction

引用

Progress in Natural Science:Materials International 2022年第6期32卷 705-714页

Designing advanced electrocatalysts for the oxygen evolution reaction（OER） is of great significance owing to its crucial role in facilitating the production of clean hydrogen energy via water splitting.To date,it has been widely accepted that a pre-oxidation process with the in-situ generation of the catalytically active high-valence metal sites is essential for promoting the OER behavior of most transition-metal-based OER catalysts,or more felicitously speaking,pre-catalysts.Hence,exploring such pre-catalysts with high pre-oxidation reactivity is of high promise.Herein,we proposed the dual elemental modulation in the cationic and anionic sites of the multi-metal Prussian blue analogue（PBA） pre-catalysts,resulting in promoted OER behavior benefitted from the efficient preoxidation ability as well as the multi-metal synergy.Detailed investigations indicate that the Co-containing multimetallic cations and mixed FeⅢCoⅢcyanide anions in NiCuCoⅡ-FeⅢCoⅢPBA（denoted as NiCuCoⅡ-FeⅢCoⅢ） are beneficial to OER catalysis owing to the high intrinsic activity guaranteed by the local Co3+active sites as well as the optimal multi-metal synergy.After the facile pre-oxidation process,additional high-valence Ni,Cu and Fe ions can be in-situ formed and serve as the active sites,thereby resulting in significantly improved OER behavior.For example,the OER current density of NiCuCoⅡ-FeⅢCoⅢexhibits 1.81 times enhancement even after 72 h continuous OER catalysis,and the required overpotential for 10 mA cm-2reduces from 288 mV for the fresh precatalyst to a remarkable record of 251 mV after the pre-oxidation-induced activation,making the optimal PBA-based catalyst a promising candidate for efficient and durable water electrolysis.

As a four-electron transfer reaction,oxygen evolution reaction(OER)is limited by large overpotential and slow kinetics.Here,we in-situ synthesized two-dimensional(2D)Ni-Fe metal-organic framework nanosheets on nickel foam(NixFe-TPA/NF,TPA=terephthalic acid)for oxygen evolution in alkaline and alkaline seawater electrolytes.In 1 M KOH,Ni3Fe-TPA/NF shows a low overpotential(η10)of 189 mV at 10 mA·cm^(-2) and an ultra-low overpotential of only 260 mV at 500 mA·cm^(-2).In alkaline seawater,Ni3Fe-TPA/NF still provides impressive OER performance,with anη10 of 265 mV.In-situ Raman characterization results show that the phase transition occurs during the OER,and Ni3FeOOH with more oxygen vacancies is in-situ formed,reducing the OER energy barrier.Density functional theory(DFT)reveals that the synergy between Ni and Fe reduces the energy barrier and accelerates the rate-determining step.In addition,the ultra-thin 2D sheet structure and the close combination of Ni3FeOOH and highly conductive NF support ensure the high catalytic OER activity.Therefore,the surface reconstruction and structural modification strategy can be used to design and prepare high-performance OER electrocatalysts for energy-related applications.
