NOVELTY - Preparing molybdenum disulfide nanosheet/carbon nitride nanosheet/graphene three-dimensional composite electrode catalyst involves forming a dispersion of molybdenum disulfide nanosheets, a dispersion of carbon nitride nanosheets, and a dispersion of graphene oxide. The molybdenum disulfide nanosheet dispersion, carbon nitride nanosheet dispersion and graphene oxide dispersion are mixed, and stirred uniformly to obtain molybdenum disulfide nanosheet/carbon nitride nanosheet/graphene oxide ternary Composite solution, where the added amount of the molybdenum disulfide nanosheets and carbon nitride nanosheets is added in weight ratio of 1-10:1-10. The added amount of the graphene oxide and molybdenum disulfide nanosheet/carbon nitride nanosheet binary composite is 1-10:1-10 in terms of mass ratio. USE - Method for preparing molybdenum disulfide nanosheet/carbon nitride nanosheet/graphene three-dimensional composite electrode catalyst. ADVANTAGE - The method enables to prepare molybdenum disulfide nanosheet/carbon nitride nanosheet/graphene three-dimensional composite electrode catalyst with large specific surface area, number of catalytic active sites, good cycle stability and excellent catalytic performance. DETAILED DESCRIPTION - Preparing molybdenum disulfide nanosheet/carbon nitride nanosheet/graphene three-dimensional composite electrode catalyst involves forming a dispersion of molybdenum disulfide nanosheets, a dispersion of carbon nitride nanosheets, and a dispersion of graphene oxide. The molybdenum disulfide nanosheet dispersion, carbon nitride nanosheet dispersion and graphene oxide dispersion are mixed, and stirred uniformly to obtain molybdenum disulfide nanosheet/carbon nitride nanosheet/graphene oxide ternary Composite solution, where the added amount of the molybdenum disulfide nanosheets and carbon nitride nanosheets is added in weight ratio of 1-10:1-10. The added amount of the graphene oxide and molybdenum disulfide nanosheet/carbon nitride nanosheet binary composite is 1-10:1-10 in terms of mass ratio. The ternary composite solution is subjected to a hydrothermal reaction to obtain a hydrogel-like product, which is dialyzed and washed with water, and freeze-dried to obtain a molybdenum disulfide nanosheet/carbon nitride nanosheet/graphene three-dimensional composite electrode catalyst. DESCRIPTION OF DRAWING(S) - The drawing shows a flowchart of the method for preparing molybdenum disulfide nanosheet/carbon nitride nanosheet/graphene three-dimensional composite electrode catalyst.
