▎ 摘  要

NOVELTY - The preparation method of graphene octahedral cuprous oxide composite material involves ultrasonically dispersing copper acetate and graphene oxide in water, uniformly mixing, stirring the mixture at room temperature for 20-30 minutes, adding 0.5-2 mol/l sodium hydroxide solution and 500-800 mu l hydrazine hydrate solution to the mixture and then stirring at room temperature for 40 minutes, centrifuging the mixture and then washing, and drying. USE - The method is useful for preparation of graphene octahedral cuprous oxide composite material, which is useful as photocatalyst for degradation of organic dye including methyl orange (claimed). ADVANTAGE - The method enables simple and economical preparation of graphene octahedral cuprous oxide composite material with high yield and photocatalytic efficiency and excellent solar energy utilization rate in environmentally-friendly manner. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for use of graphene octahedral cuprous oxide composite material as photocatalyst.
