A Green Synthesis Strategy for Cobalt Phosphide Deposited on N, P Co-Doped Graphene for Efficient Hydrogen Evolution.

ABSTRACT: The exploitation of electrocatalysts with high activity and durability for the hydrogen evolution reaction is significant but also challenging for future energy systems. Transition metal phosphides (TMPs) have attracted a lot of attention due to their effective activity for the hydrogen evolution reaction, but the complicated preparation of metal phosphides remains a bottleneck. In this study, a green fabrication method is designed and proposed to construct N, P co-doped graphene (NPG)-supported cobalt phosphide (Co₂P) nanoparticles by using DNA as both N and P sources. Thanks to the synergistic effect of NPG and Co₂P, the Co₂P/NPG shows effective activity with a small overpotential of 144 mV and a low Tafel slope of 72 mV dec^-1 for the hydrogen
