NOVELTY - Method for producing a composite of molybdenum disulfide-graphene-metal particles involves (a) electrically blasting a metal wire in a solvent containing a graphene precursor to form graphene-coated metal particles, and reacting the graphene-coated metal particles with a molybdenum disulfide precursor through a hydrothermal synthesis method, and (b) forming molybdenum disulfide on the surface of the graphene-coated metal particles. USE - The method is used for producing a composite of molybdenum disulfide-graphene-metal particles (claimed). ADVANTAGE - The method saves time, provides high yield of product, reduces use of high cost platinum catalyst and improves efficiency of molybdenum disulfide catalyst, maximizes specific surface area of molybdenum disulfide, and is cost-effective. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) a method (i) for producing a composite of molybdenum disulfide-graphene nanopowder comprising (A) forming molybdenum disulfide on the surface of graphene nanopowder by reacting graphene nanopowder with a molybdenum disulfide precursor by hydrothermal synthesis, and (B) doping a platinum atom (Pt) to the surface of the graphene nanopowder on which the molybdenum disulfide is formed; (2) a complex of molybdenum disulfide-graphene-metal particles comprising an inner particle and a graphene coating layer, and molybdenum disulfide sheets formed in the form of a sheet on the surface of the composite particle, where the molybdenum disulfide sheets are in contact with the surface of the composite particle at a part of the sheet surface or edge, and the edge or other part of the face extends to protrude outwardly from the composite particle; and (3) a composite of molybdenum disulfide-graphene powder comprising graphene powder, and molybdenum disulfide sheets formed in a sheet form on the surface of the graphene powder, where the molybdenum disulfide sheets, a part of the sheet surface or edge is in contact with the surface of the graphene powder, and the edge or other part of the surface is characterized in that it extends so as to protrude outward from the graphene powder.
