过渡金属磷化物的改性方法及其在电化学析氢中的应用

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.
