NOVELTY - Preparing oxidized graphene by non-hydrogen peroxide quenching reaction involves mixing graphite and concentrated sulfuric acid, stirring, mixing graphite and the concentrated sulfuric acid in an amount of 25-500ml concentrated sulfuric acid per gram of graphite, adding oxidant, then raising the temperature to 15-100degrees Celsius, continuously stirring, adding water to the solution gradually becomes yellow to obtain product. USE - Method for preparing oxidized graphene by non-hydrogen peroxide quenching reaction used in electronic devices. ADVANTAGE - The method does not need to add hydrogen peroxide, reduces the possibility of GO is reduced, and is more intuitive and controllable in the process and safety environment-friendly, and greatly reduces the production cost, brings great advantages in the industrial production of graphene oxide. The graphene oxide directly generates bright yellow solution, so as to simplify the production process, realizing environment- friendly, safety high-quality graphene oxide with low cost. In the process of preparing graphene oxide of the invention, the prepared product is bright yellow, it shows that the product prepared by the invention has higher oxidation degree and excellent performance.
