▎ 摘　　要

NOVELTY - The preparation of graphene-supported copper nanoparticles involves thoroughly stirring and mixing freeze-dried graphene oxide and copper salt aqueous solution and filtering to obtain graphene oxide containing copper ions, drying in vacuum to obtain brown cake-like product, grinding the brown cake and heating under inert gas protection. USE - Preparation of graphene-supported copper nanoparticles used in catalysis. ADVANTAGE - The method enables preparation of graphene-supported copper nanoparticles by simple process.
