Abstract

Graphene Oxide, the most recent nano scale form of carbonaceous material, has attracted much attention recently because of its unique electrical, thermal and mechanical properties, and its tremendous applications in different fields such as in optical, electronic, and catalytic fields. Graphite powder was used as a raw source for the synthesis of graphene oxide via modified Hummer's method. The structural and physiochemical properties of the synthesized product were investigated using techniques, Scanning Electron Microscopy (SEM), Fourier Transform Infrared Spectroscopy (FTIR), X-Ray Diffraction Spectroscopy (XRD) and Energy-dispersive X-ray spectroscopy (EDS). The FTIR

analysis of graphene oxide was found to exhibit several characteristic absorption bands C=O, C=C, C-OH, and C-O suggesting that oxygen-containing groups were introduced into the graphene. The XRD pattern of the prepared graphene oxide showed a sharp peak centered at 2O =9.388, which resembled to the graphene oxide. The SEM micrographs of synthesized graphene oxide demonstrated the layered structure, which affords homogeneous ultra thin graphene films. The EDS analysis of the graphene oxide showed that the sample contains C and O, no other impurity was detected indicating the final product is free of impurities. C and O content was detected 60.90 and 39.10 weight% respectively.
