NOVELTY - Preparing reduced graphene oxide by dielectric barrier discharge plasma comprises (i) placing graphene oxide between two electrodes in a plasma device, (ii) passing discharge gas into plasma device, (iii) applying high voltage on the two electrodes, and carrying out plasma treatment to obtain final product. USE - The method is useful for preparing reduced graphene oxide by dielectric barrier discharge plasma. ADVANTAGE - The method has convenient operation, low energy consumption, no pollution, high production efficiency, utilizes simple device, (carbon source conversion rate reaches more than 90%), and increases the specific surface area from 100 m2 g to 400 m2/g of the reduction method, and low preparation cost; and is suitable for industrial production.
