Present work reports on the synthesis, characterization and photocatalytic activity of graphene oxide (GO). Recent studies have indicated GO to be a potential candidate for the treatment of textile wastewater. Here, GO was synthesized using solo-thermal method. Characterization of GO was performed using X-Ray Diffraction (XRD), Fourier Transform Infrared Spectroscopy (FTIR) and Scanning Electron Microscopy (SEM). The photocatalytic activity of GO was investigated for the degradation of the textile dye Methylene blue (MeB) under visible light. The result showed GO nanosheets exhibited 79% photocatalytic activity. The study suggested that GO nanosheets may be an excellent material for the treatment of wastewater for environment applications.
