▎ 摘　　要

NOVELTY - Producing industrial graphene by oxidation-reduction process, comprises e.g. mixing concentrated sulfuric acid in flake graphite, heating, and reacting, to obtain acidic mixture, cooling acid mixture, orderly adding potassium permanganate and water to react, after finishing reaction, adding hydrogen peroxide to obtain graphite oxide solution, centrifuging, washing graphite oxide solution in water to neutral, formulating the solution into a suspension, treating under ultrasonic, to obtain graphene oxide solution, heating graphene oxide solution, adding hydrazine hydrate, drying, and crushing. USE - The method is useful for producing industrial graphene by oxidation-reduction process (claimed). ADVANTAGE - The method has short production period, high yield, low production cost, and is easy to achieve industrialization.
