NOVELTY - Preparing graphene by electrochemical anode stripping, comprises (1) mixing sulfuric acid solution and 1-(4'-sulfo-1'-phenylazo)-2-naphthol-6-sulfonic acid disodium salt as electrolyte, or using sodium hydroxide, hydrogen peroxide and 1-(4'-sulfo-1'-phenylazo)-2-naphthol-6-sulfonic acid disodium salt as electrolyte; (2) using the graphite rod/graphite foil to be stripped as anode, and other graphite rod as cathode, switching on power supply in oil bath while keeping the electrolyte stirring; (3) pre-stripping the graphite rod/graphite foil to be stripped off, increasing the pressure for formal stripping, and stripping off all the graphite rods/graphite foil to be stripped off until the current is 0; and (4) performing ultrasonic treatment on product obtained in step (3) to obtain a graphene aqueous solution. USE - The method is useful for preparing graphene by electrochemical anode stripping. ADVANTAGE - The graphene: can be kept for long time without precipitation.
