NOVELTY - Preparing graphene-two dimensional noble metal atom cluster composite material comprises noble metal atoms on the surface of graphene two dimensional clusters in the form of deposition, i.e. graphene is deposited on the vertical dimension of noble metal atom thickness is ultra-thin, with single layer or double layer atom thickness, then depositing on the graphene layer on the noble metal atom having many nano size, where the preparation of the composite material comprising e.g. (i) taking natural graphite, oxidation, ultrasonic dispersion, and (ii) dropping on glass electrode surface. USE - The method is useful for preparing graphene-two dimensional noble metal atom cluster composite material (claimed). ADVANTAGE - The method can increase the performance and enlarges the using range. DETAILED DESCRIPTION - Preparing graphene-two dimensional noble metal atom cluster composite material comprises noble metal atoms on the surface of graphene two dimensional clusters in the form of deposition, i.e. graphene is deposited on the vertical dimension of noble metal atom thickness is ultra-thin, with single layer or double layer atom thickness, then depositing on the graphene layer on the noble metal atom having many nano size, where the preparation of the composite material comprising (i) taking natural graphite carrying out oxidation to obtain graphite oxide, using graphite oxide, carrying out, ultrasonic dispersion in an aqueous solution to obtain graphite oxide solution, (ii) using graphite oxide solution dropping on the glass electrode surface, slowly drying, (iii) using glass electrode placing into mediated metal ion (lead or copper) and mixed solution of noble metal ion and, using glass electrode at a potential range carrying out under potential deposition of metal, dissolving and peeling off, (iv) using glass electrode repeatedly carrying out voltampere scan in the glass electrode potential range, through multi-time under electric position deposition, dissolving and peeling off, finally using deposition of glass electrode of noble metal, washing with distilled water and drying.
