An efficient and facile production of highly favorable graphene oxide (GO) via modified Hummers’ method at different oxidation degrees was successfully demonstrated. The formation of oxygen containing functional groups and their effects on GO structural properties were analyzed by UV–visible spectrophotometry (UV–vis), Fourier transform infrared spectroscopy (FTIR), x-ray diffraction (XRD) and Raman spectrophotometer. The presence of hydroxyl (-OH), carboxyl (-COOH), epoxy (COC) and carbonyl (CO) groups in GO and their intermolecular interaction were analyzed by FTIR. XRD pattern of GO showed the dominant peak at 10.8° with interlayer spacing (0.82 nm) larger than pristine graphite (0.34 nm) owing to the addition…..
