Coupled W-Co 2 P 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 Co 2 P nanosheets onto nickel foam (W@Co 2 P/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.
