Heterostructured Co2P Nanocomposite Embedded in a N, P Co-Doped Carbon Layer as a High Performance Electrocatalyst for Overall Water Splitting

Hydrogen is the mainstream future energy source because of its high density and environmentally-friendly properties. In this study, Fe-Co2P/NPC materials were prepared by wet chemical synthesis method, in which Fe-Co2P nanowires wrapped N, P co-doped carbon layers (NPC) under aging phosphorylation strategies. When Fe-Co2P/NPC/NF was subjected to hydrogen evolution reaction (HER) oxygen (OER), overpotential only 73 mV 217 reach current 10 mA cm−2, respectively. cathode anode both Fe-Co2P/NPC/NF, a cm−2 achieved with 1.56 V. This work provides new idea for design preparation non-precious metal-based transition metal phosphide catalysts.
