NOVELTY - Halogenated graphite is obtained by reacting expanded graphite with a halogen simple substance under microwave radiation. USE - Preparation of halogenated graphite for use in preparation of halogenated graphene (all claimed). ADVANTAGE - The method enables simple, quick and economical large-scale preparation of halogenated graphite and halogenated graphene with high yield. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) halogenated graphite; (2) preparation of halogenated graphene, which involves dispersing and centrifuging halogenated graphite, and collecting supernatant; and (3) halogenated graphene comprising halogen and graphite bonded by carbon-halogen covalent bond. The content of halogen in the halogenated graphene is 0.5-4 wt.%. The halogen is bromine or chlorine.
