The graphitic-like carbon nitride (C₃N₄) and graphene oxide (GO) were respectively prepared by one step semi-enclosed pyrolysis and improved Hummers method. Following the reduced graphene oxide/C₃N₄ (RGO/C₃N₄) composites were fabricated via a photo-reduction route. The as-prepared samples were characterized by X-ray diffraction (XRD), Field emission scanning electron microscopy (FESEM), X-ray photoelectron spectroscopy (XPS), UV-Vis diffuse reflectance absorption spectroscopy (DRS), Photoluminescence (PL) and Fourier transform infrared spectroscopy (FTIR). The photocatalytic activity of samples was evaluated under visible light irradiation using Rhodamine B(RhB) as probe molecule. The experimental results show that the introduction of RGO could considerably enhance photocatalytic activity, and the 6.0% RGO/C₃N₄ composite exhibits the best photocatalytic performance. The significantly enhanced photocatalytic activity for the present composite originates from the electron-accepting and electron-transportation property of RGO, which inhibits the recombination rate of photogenerated electron-hole pairs.
