▎ 摘　　要

NOVELTY - Organometallic compounds and/or coordination compound and additive are mixed, heated, and separation and purification processes are carried out by placing in acidic solution under reflux condition. Impurities are removed from the resultant material to obtain graphene micro sheet-diamond composite. USE - Manufacture of graphene micro sheet-diamond composite (claimed). ADVANTAGE - The method efficiently and economically provides graphene micro sheet-diamond composite at low reaction temperature, by simple method.
