摘　　要：过渡金属磷化物催化活性高、稳定性好,是电催化析氢的良好催化剂。然而,实现过渡金属磷化物在电解水制氢领域的大规模应用,还需要进一步提升其催化性能。本文以过渡金属磷化物的组成变化为出发点,从金属/磷(M/P)化学计量比的角度对过渡金属磷化物的性能进行了总结,介绍了其常见的制备方法,详细综述了元素掺杂、构造缺陷、构建界面工程、耦合炭材料、调控微观结构、改善材料浸润性等改性方法对过渡金属磷化物电催化制氢性能的影响。最后在新型磷源的开发、测试标准化、晶面调控等方面对过渡金属磷化物的发展趋势进行了展望。Transition metal phosphides are efficient catalytic materials for electrochemical hydrogen production because of their high catalytic activity and good stability.However,realizing their large-scale application in electrolytic water hydrogen evolution needs further improvement on the catalytic performance.Based on the composition of transition metal phosphides,their properties were summarized in terms of the metal/phosphorus(M/P)stoichiometric ratio.In addition,the common preparation methods of transition metal phosphides were introduced,and the influence of the modification methods such as element doping,structural defects,interface engineering and coupling of carbon materials,microstructure regulation,and wettability improvement on the electrocatalytic hydrogen evolution were reviewed in detail as well.The development trend of transition metal phosphides is also prospected from the aspects of exploiting new phosphorus source,standardizing electrochemical tests and regulating the crystal planes.
