NOVELTY - The method involves adding 15 mg/mL strong alkali aqueous solution to 10 mg/mL graphene oxide solution and mixing uniformly to obtain a suspension and the volume ratio of the strong alkali solution to the graphene oxide solution is 6:1 to 1:1. The solution is placed in a water bath at 85degrees Celsius-95degrees Celsius to react for 24-30 hours to obtain the reduced graphene and dried to a solid, after adding 0.1-0.4g vitamin C and 0.1g Hans ester 1,4-dihydropyridine to the suspension. The dried solid is washed in turn by ethanol and deionized water to obtain a final product. A strong base is selected from two of sodium hydroxide, potassium hydroxide, lithium hydroxide or calcium hydroxide. The graphite oxide is oxidized to obtain graphite oxide, and water is added ultrasonically to obtain the graphene oxide solution. USE - Method for preparing high specific surface graphene. ADVANTAGE - The specific surface area of the graphene is greater than 1000 m2/g and the cost is low. The environmental friendliness is high.
