▎ 摘  要

In this paper, a facile and a fast synthesis process of reduced graphene oxide (rGO) is introduced by using a modified Marcano method. A modification of the chemical synthesis method was developed, which uses a small amount of strong acids, a low oxidation temperature and a short stirring process. X-ray diffraction (XRD) pattern and Fourier transform infrared spectrometry (FTIR) spectra confirmed that rGO was successfully synthesized. Scanning electron microscopy (SEM) and transmission electron microscopy (TEM) images showed rGO in sheet form. Based on energy dispersive x-ray spectrometry (EDX), the surface of the prepared rGO sample was dominated by similar to 90% of C atoms. Four-point probe measurements showed the electrical conductivity of the prepared rGO sample at 1180 S m(-1). Based on the electrochemical impedance spectrometry (EIS) results gives 2.1 Omega charge transfer resistance between the electrode and the electrolyte to the prepared rGO sample. This study provides a new perspective on rGO synthesis using a wet chemical process.
