- 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.
