▎ 摘　　要

NOVELTY - A regular graphene is prepared by chemical gas phase deposition by placing metal foil or substrate with metal catalyst in a reactor without oxygen and water, raising temperature of metal foil or substrate to 800-1050 degrees C, and adding carbon source to the reactor for reaction to obtain regular graphene. USE - Method of preparing regular graphene (claimed). ADVANTAGE - The method is simple and convenient to operate, and can obtain regular graphene having equiangular hexagonal which is suitable for large scale production. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a regular graphene.
