Reduced graphene oxide (RGO) is one of the most effective way to obtain the graphene. In this study, RGO was obtained by reduction of graphene oxide (GO) synthesized by a modified Hummers method. The transparent structures of RGO have been identified through SEM images. The ratio of carbon (C) was found to be approximately 89% by SEM/EDX analysis. It was proven by FT-IR analysis that hydroxyl, carbonyl, epoxy and alkoxy bonds in GO structure were removed from RGO structure. On the other hand, RAMAN spectroscopic studies showed that the new sp <sup>2 </sup> structures occurred, and the amount of regular structures increased. XRD analysis indicated that d-spacing between the layers of RGO decreased from 0,83 nm to 0,36 nm due to the degradation of functional groups during the chemical process, which were formed in the oxidation process. <strong> </strong> </p>}, number={2}, publisher={Sakarya University}
