▎ 摘　　要

NOVELTY - The method involves irradiating light after processing graphite powder with ultrasonic wave with underwater, and adding surfactant and metal ion to the obtained product for manufacturing the metal-graphene nano-composite, where particle size is 1-20 micrometer. The surfactant is selected from sodium dodecyl sulfonate, cetyltrimethylammonium bromide, cetyl trimethyl ammonium chloride, dioctyl sodium sulfo succinate or sodium oleate. The metal ion is made of gold, silver, palladium, platinum, copper, molybdenum, nickel, ruthenium or rubidium. USE - Method for preparing metal-graphene nano-composite that is utilized in alcohol oxidation catalyst, organic reaction catalyst and electric chemistry reaction catalyst. ADVANTAGE - The method enables manufacturing the nano-composite from graphite without separating oxidation and reduction process so as to ensure economic effect and simple manufacturing process. The surfactant does not remain in the nano-composite during manufacturing process. The method enables eliminating the need of reducing agent. DESCRIPTION OF DRAWING(S) - The drawing shows a photographic view of a metal-graphene nano-composite.
