NOVELTY - Preparing high conductive sulfonated graphene by graphite reduction comprises (1) dissolving reaction raw materials, alkali metal and catalyzer in an organic solvent, and reacting at the first reaction temperature to obtain reduction intermediate, and (2) adding a sulfonating reagent to the graphene reduction intermediate obtained in step (1), reacting at the second reaction temperature, washing and filtering to obtain final product. The reaction raw material is natural graphite including flake graphite, block graphite or earthy graphite. USE - The method is useful for preparing high conductive sulfonated graphene by graphite reduction. ADVANTAGE - The method: utilizes low cost natural graphite as raw material; adopts the graphite reduction strategy, which ensures the prepared sulfonated graphene has few lattice defects; introduces sulfonate groups on graphite, and thus it ensures the prepared sulfonated graphene has high dispersibility and high electrical conductivity of intrinsic graphene.
