NOVELTY - Preparing porous graphene dispersion by electrochemical method, comprises preparing electrolyte, performing microwave pretreatment of the graphite material, taking pretreated graphite material as anode and metal electrode or graphite electrode as cathode, and electrolytically peeling the graphite material in electrolyte to obtain exfoliated material, collecting the exfoliated material, washing and drying to obtain graphite intercalation compound, adding graphite intercalation compound into a dispersion medium solvent and ultrasonically processing to obtain a porous graphene dispersion. USE - The method is useful for preparing porous graphene dispersion by electrochemical method. ADVANTAGE - The method: is simple and efficient, and one-step electrochemical reaction; has mild reaction conditions, less equipment requirements, and low cost; and is environmentally friendly and suitable for industrial production.
