Iron group transition metal phosphides (TMPs, M= Fe, Co, Ni) have been considered as promising noble-metal-free cocatalysts for the photocatalytic hydrogen (H2) generation. However, the impact on the H2 generation activity in correlation with the types of metal in TMPs still remains unresolved. ...

Electrochemical water splitting is a promising technology for mass hydrogen production. Efficient, stable, and cheap electrocatalysts are keys to realizing this strategy. However, high price and preciousness of commonly used noble metal based catalysts severely hinder this realization. Herein, w...
