Abstract
In the recent research work, synthesis of Graphene oxide was done by treating graphite powder with KMnO4 and a mixture of H2SO4/H3PO4 and then reduced with ascorbic acid to produce graphene oxide. A method that was approved for this purpose was Tour method. X-ray Diffraction (XRD), Raman Spectroscopy and Scanning Electron Microscopy (SEM) were used for the characterization of the obtained samples. Structural analysis was determined with the help of X-ray diffraction (XRD) using CuKα radiation (λ=0.15405nm). Raman Spectroscopy was used for chemical analysis. Surface characterization was done with the help of Scanning electron microscopy. XRD pattern obtained through (SEM) shows that GO and RGO were successfully synthesized at 9.2° and 25.1° peaks respectively. Results from GO and RGO Raman spectra samples indicate that oxidation was effective and there was not a complete elimination of oxygenated group in the RGO sample. In SEM images, RGO exhibits wrinkled and agglomerated structures. Needle like structures were visible at higher magnification.
