▎ 摘　　要

NOVELTY - Preparation of graphene comprises attaching organic matter on the support to form film, heating at high temperature in oxygen free environment attached with support for organic film to carry out carbonization and graphitization, controlling temperature at not less than 750 degrees C, cooling, and obtaining support on graphene layer. USE - Method of preparation of graphene (claimed). ADVANTAGE - The method does not need catalyst, directly grows on the needed support, is very simple and convenient, and is suitable for industrial production. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram of the preparation of graphene.
