▎ 摘　　要

NOVELTY - Preparation of controllable catalytic active species-containing amorphous molybdate/graphene catalyst involves dispersing ammonium tetrathiomolybdate and graphene oxide in a solvent, coating on the surface of a load electrode, drying the volatile solvent to obtain a precursor electrode, placing the precursor electrode in a vacuum cavity, and plasma treating. USE - Preparation of controllable catalytic active species-containing amorphous molybdate/graphene catalyst used for hydrogen evolution by electrolysis of water (all claimed). ADVANTAGE - The method is simple and fast. The time needed for the whole preparation is less than one hour. The content of catalytic active species can be controlled by changing the plasma processing time to obtain non-noble metal hydrogen evolution reaction catalyst having excellent catalytic performance.
