▎ 摘　　要

NOVELTY - A polystyrene-polyvinyl pyridine micelle is prepared for loading metal salt, and adhered on substrate containing catalyst. The resulted substrate adhered with polystyrene-polyvinyl pyridine micelle is supplied into a reactor, polystyrene-polyvinyl pyridine micelle is resolved under reduced atmosphere, graphene film is generated on the surface of substrate and metal salt is reduced in to metal nano particles. The obtained metal nano particles are uniformly dispersed on graphene film, to obtain graphene-metal nano particles composite material. USE - Preparation of graphene-metal nano particles composite material (claimed). ADVANTAGE - The graphene-metal nano particles composite material is prepared by simple and highly efficient method.
