Abstract
A reduced graphene oxide (RG-Os) is the promising material that has special properties in electronics and optics. Reduced graphene oxide by using supercritical solvothermal method is one of the considerable methods. Furthermore, RG-Os was prepared in short reaction time (2 hour) and using common solvent (methanol) which are environmental friendly and scalable for mass production. X-Ray Photoelectron Spectroscopy (XPS) and Fourier Transform Infra Red (FTIR) showing increase intensity of C=C bond. High deoxygenating level was showed by the high value of carbon/oxygen ratio, analyzed by XPS and CHNOS (Carbon-Hydrogen-Nitrogen- Oxygen-Sulfur) Analyzer. Powder X-ray diffraction (XRD) analysis of RG-Os shows a single broad peak at 25.1° 2Θ angle, verifying the exfoliation of graphitic sheets.
