Abstract

The invention relates to a preparation method of a catalyst material for hydrogen production by virtue of electrolysis of water. The preparation method comprises the steps of soaking graphite carbon nanostructure-graphene composite carbon paper in a precursor solution of molybdenum and sulfur, carrying out a hydrothermal reaction or a solvothermal reaction, and then repeatedly washing to obtain a molybdenum sulfide and graphite carbon nanostructure-graphene composite carbon paper material, namely the catalyst material. Compared with the prior art, the catalyst material can be directly used as a catalytic electrode material for hydrogen production by virtue of electrolysis of water without glassy carbon electrode coating treatment; the preparation method is green and safe, simple in process and low in raw material cost, can realize large-scale continuous production and has wide application prospect in the field of hydrogen production by virtue of electrolysis of water.
