USE - Method for preparing graphene molybdenum disulfide-graphene composite material (claimed). ADVANTAGE - The method enables preparation of graphene molybdenum disulfide-graphene composite material by one-step process. DETAILED DESCRIPTION - Method for preparing graphene molybdenum disulfide-graphene composite material, involves (1) adding molybdenum disulfide powder to intercalation solution for intercalation reaction, drying to obtain intercalated molybdenum disulfide powder, reacting molybdenum disulfide powder with potassium chlorate, sodium nitrate, 98% concentration of sulfuric acid and 30% concentration of hydrogen peroxide in a ratio of 1 g:(1-4) g:(0.5-2) g:(9-40) mL:(4-20) mL, (2) mixing intercalated molybdenum disulfide powder and protein substances with water, stirring evenly, drying, grinding to obtain precursor powder, (3) carrying out reduction reaction of precursor powder under protective gas, removing the reaction product and grinding to obtain graphene molybdenum disulfide-graphene composite material. The intercalation solution is selected from potassium chlorate, sodium nitrate, concentrated sulfuric acid and hydrogen peroxide. The ratio of intercalated molybdenum disulfide powder, protein and water is 2 g:(2-7) g:(20-70) g.
