Overview of Transition Metal Phosphide Catalysts and Hydrogen Production by Electrolyzed Water

Hydrogen energy is a green and efficient secondary energy source. With the help of cheap non-precious metal catalysts， electrolysis of water to produce hydrogen has attracted widespread attention because of its low cost and high efficiency. The transition metal phosphide can expose more coordinated unsaturated surface atoms due to its unique nearly spherical triangular prism unit structure， so it exhibits excellent catalytic activity， strong corrosion resistance and high efficiency in the production of hydrogen from electrolyzed water. This article mainly reviews the preparation methods of transition metal phosphides and their application and performance improvement in electrocatalytic hydrogen evolution. Finally， some problems that need to be solved in transition metal phosphide catalysts are discussed， which is beneficial to the development of other non-noble metal electrolyzed hydrogen production catalysts.
