Reduced graphene oxide (RGO) grafted W doped BiVO4 (WBVO) hybrids have been obtained using twostep wet-chemical approach. At first, WBV was synthesized by hydrothermal method in strong-acid condition. And second, the WBVO/GO mixture was transformed into WBVO/RGO hybrids by hydrothermal treatment under ethanol-water condition. The photocatalytic activity of WBV/RGO can be optimized by controlling the content of RGO at 4 wt%. Such a novel composite photocatalyst might find potential application for air purification and waste water treatment. (C) 2014 Elsevier B.V. All rights reserved.
