▎ 摘　　要

NOVELTY - Graphene is synthesized by mixing solid organic acid and catalyst, placing mixture in a reactor under protection of inert gas or reducing gas atmosphere, reacting, then cooling reaction system to room temperature to obtain solid product, washing the solid product, filtering and drying to obtain the graphene product. USE - Method for synthesizing graphene (claimed). ADVANTAGE - The method has no pollution, low cost and simple operation, and is suitable for large-scale.
