A series of GO modified AgCl/Ag3PO4 composites were prepared by a simple method. The samples were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), UV-vis diffuse reflectance spectra (DRS) analysis and Brunauer-Emmett-Teller (BET) specific surface area analysis. The photocatalytic performance of the samples was measured by the degradation of dye methylene blue (MB) and O-2 evolution under visible light irradiation. The results indicated that the couple of AgCl and GO could effectively enhance the photoactivity and stability in comparison with bare Ag3PO4. From the analysis, it can be inferred that GO sheets could accelerate the separation of electron hole pairs and also improve the light absorption ability in comparison with bare Ag3PO4 and AgCl/Ag3PO4. Additionally, an optimum amount of GO added in the composite was obtained. Copyright (C) 2014, Hydrogen Energy Publications, LLC. Published by Elsevier Ltd. All rights reserved.
