Abstract:
A high-performance and novel photocatalyst of BiVO4-reduced Graphene Oxide (BiVO4-rGO) nanocomposite was prepared by a facile hydrothermal method. The photocatalyst was characterized by X-ray diffraction, X-ray photoelectron spectroscopy, scanning electron microscopy, transmission electronic microscopy, UV-Vis diffusion reflectance spectroscopy, photoluminescence spectroscopy and UV-Vis adsorption spectroscopy, respectively. The visible-light photocatalytic activity was evaluated by oxidation of methyl orange (MO) under simulated sunlight irradiation. The results show that the BiVO4-rGO nanocomposites exhibit enhanced photocatalytic performance for the degradation of MO with a maximum removal rate of 98.95% under visible light irradiation as compared with pure BiVO4 (57.55%) due to the increased light absorption intensity and the degradation of electron-hole pair recombination in BiVO4 with the introduction of the rGO.
