Coupled W–Co₂P hybrid nanosheets as a robust bifunctional electrocatalyst for hydrazine-assisted hydrogen production

Herein, we put forward a novel electrode by electrochemically integrating metal W species and Co2P nanosheets onto nickel foam (W@Co2P/NF), which delivers excellent bifunctional activity for both the HER and HzOR. The hydrazine assisted water electrolyzer provides a small cell potential of 0.18 V at 100 mA cm-2 and stability for hydrogen generation, which is superior to most of the other bifunctional materials.
