Abstract: Oxidized graphene oxide (GO) was prepared by means of the modified Hummers method,and it was re- duced to graphene (RGO) respectively by using ascorbic acid (LAA),tea polyphenols (TP) and the LAA/TP two-component reduction system as a reductant.Then,the conductivity,Raman spectroscopy,X-ray diffraction pattern and X-ray photoelectron spectroscopy of the obtained RGO were determined,and the morphology of the RGO prepared by LAA/TP was also characterized by means of the scanning electron microscopy,the transmission electron microscopy and the atomic force microscopy.The results show that there exists a synergistic effect between the two-component reduction system of LAA/TP,and the reduction effect of the system is better than that with only single component,and that the obtained RGO is of a monolayer structure.In addition,the mechanism of the syner- gistic effect between LAA and TP was also explained.
