▎ 摘  要

NOVELTY - Graphene oxide preparation involves mixing concentrated sulfuric acid and graphite with fuming nitric acid, and then lowering temperature. Potassium permanganate, hydrogen peroxide and water are added to obtain the graphene oxide. The mixing and stirring are carried out 0.5-1.5 hours. USE - Method for preparing graphene oxide (claimed). ADVANTAGE - The method prepares the graphene oxide in a simple and cost-effective manner. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic appearance photograph of the graphene oxide.
