▎ 摘　　要

NOVELTY - A silver/graphene composite material is obtained as follows. A graphene oxide-ethanol colloidal suspension is prepared by ultrasonically dispersing graphite powder washed with distilled water in absolute ethyl alcohol. Under strong stirring condition, silver nitrate is added the graphene oxide-ethanol colloidal suspension, stirred, and ultrasonically treated. The formed silver/graphene oxide compound is reduced by microwave method to obtain a silver/graphene composite material. USE - Silver/graphene composite material is used for rhodamine B catalytic applications (claimed). ADVANTAGE - The silver/graphene composite material has excellent catalytic activity with respect to rhodamine B.
