摘　　要：近年来,能源危机、环境污染等问题导致了人们对开发高效清洁能源的迫切需求。氢气作为一种具备广泛应用前景的可替代能源,可通过电解水制备。然而,电解水制氢过程主要受制于阳极缓慢的析氧反应(oxygen evolution reaction,OER)过程。镍铁基层状双氢氧化物(nickeliron layered double hydroxide,NiFe-LDH)由于其具备独特的层状结构、成本低廉、含量丰富且催化性能优异等特点,近年来被广泛研究。综述了通过晶格掺杂、空位缺陷和表面修饰对NiFeLDH化合物进行改性的最新研究进展,简要讨论了改性NiFe-LDH化合物研究过程中遇到的挑战和前景。In recent years,the energy crisis,environmental pollution and other problems have led to the urgent need to develop efficient and clean energy.As an alternative energy with wide application prospects,hydrogen can be produced by electrolyzing water.However,the hydrogen production from electrolyzed water is mainly limited by the slow oxygen evolution reaction(OER)process at the anode.Nickel-iron layered double hydroxide(NiFe-LDH)has been widely studied in recent years because of its unique layered structure,low cost,abundant content and excellent catalytic performance.The latest research progress on the modification of NiFe-LDH compounds by lattice doping,vacancy defects and surface modification was reviewed,and the research challenges and prospects of modified NiFe-LDH compounds were briefly discussed.
