▎ 摘　　要

A simple method is reported for the preparation of graphite oxide (GO) and graphene using KClO(3)/NaNO(3)/H(2)SO(4) and Na(2)S as oxidizing agent as oxidizing and reducing agents respectively. The formation of GO and graphene have also been confirmed by X-ray diffraction studies, UV-visible, spectroscopy, FTIR and Raman spectroscopy. The morphology, surface charge characteristic and thermal stability behaviour have been studied by SEM/TEM, Zeta potential measurements, thermogravimetric analysis.
