Crystalline–amorphous Ni–Ni(OH)2 core–shell assembled nanosheets exhibit outstanding electrocatalytic activity and stability for hydrogen evolution under alkaline conditions.
Herein, we present hierarchical Mo-doped NiCoP@carbon microspheres, which exhibits noticeable enhancement of catalytic activity and fast kinetics for hydrogen evolution. An overpotentials of 74.6 mV at 10 mA cm-2 and...
