▎ 摘  要

NOVELTY - Graphene is prepared by adding halobenzene in an organic solvent in presence of a catalyst to form graphene suspension, filtering suspension, washing filter residue and drying to remove solvent and unreacted halobenzene to obtain graphene oxide and catalyst; and adding graphene oxide with an acid, then filtering, and washing residue with water and drying to obtain graphene product. USE - Method of preparing graphene (claimed). ADVANTAGE - The preparation is convenient to operate and has simple post-treatment step.
