▎ 摘　　要

NOVELTY - Manufacturing copper oxide/graphene nanocomposite of sea urchin structure, comprises (a) mixing and stirring copper acetate, graphene oxide and distilled water to form copper ions/graphene oxide complexes; (B) injecting the copper ions/graphene oxide complexes into an ammonia water to prepare a cuprammonium complex; (C) heating the cuprammonium complex, and mixing and stirring with sea urchin copper oxide to induce the growth of nanostructures at a surface of a graphene structure; and (D) precipitating the copper oxide/graphene nanocomposite. USE - The method is useful for manufacturing copper oxide/graphene nanocomposite of sea urchin structure (claimed). ADVANTAGE - The method is capable of manufacturing the copper oxide/graphene nanocomposite in a simple and cost-effective manner.
