| Abstract: | A kind of green environmental protection and efficient preparation method of graphene oxide was studied. With natural graphite as raw material, the potassium ferrate as a strong oxidizer, by intercalating method, graphene oxide was prepared. By scanning electron microscopy (SEM) and transmission electron microscopy (TEM), X-ray (XRD), infrared spectrum (IR), morphology and structure of the sample were characterized. By cyclic voltammograms side test (CV), the electrochemical behavior of the graphene oxide material was studied. The results show that 8 000 mesh graphite is the optimal choice to synthesize graphene oxide with better electrochemical behavior, specific capacitance of 126.2 F/g. |
