Abstract In this paper, graphene oxide (GO) was prepared by the modified Hummer method,reduced graphene oxide (RGO) was prepared by reducing GO with strong reducing ability and environment-friendly vitamin C and tea polyphenols as reducing agents. Fourier transform infrared spectroscopy (FT-IR) showed that the absorption peak of the oxygen-containing functional group of the reduced RGO was significantly reduced,and X-ray diffraction (XRD) pattern observed the change of the absorption peak position of GRO after reduction. The thickness of the sample was observed by atomic force microscopy (AFM). These characterization data indicate that the two reducing agents used in the experiment successfully reduced GO to produce RGO.
