▎ 摘  要

NOVELTY - One-step synthesis of graphene/copper nano compound material comprises dispersing graphite oxide (0.05-5 g/l) into mixed solution of water and ethanol, adding copper salt (0.01-0.1 mol/l), dispersing ultrasonically and uniformly, transferring reaction system added with copper salt to water bath of 60-100 degrees C, slowly adding concentrated ammonia solution of hydrazine hydrate under stirring, where concentration range of hydrazine hydrate is 0.01-0.1 mol/l, continuously performing reaction for 30-120 minutes, centrifuging, filtering and drying to obtain graphene/copper nano compound material. USE - The method is useful for preparing graphene/copper nano compound material. ADVANTAGE - The method: saves energy; is simple and quick; performs simultaneous reduction of graphene oxide and copper ion in one step, thus economical; and uniformly loads the nano copper on the surface of graphene sheet.
