A highly active visible light-induced BiVO_4 photocatalyst was prepared by a simple co-precipitation method using ammonia solution as a pH adjustor and Triton X-100(TX100) as a structure directing agent.The physical properties of the prepared BiVO_4photocatalyst were investigated by several techniques such as X-ray diffractometer(XRD),Brunauer-Emmett-Teller(BET) surface area measurement,scanning electron microscopy(SEM),energy dispersive analysis(EDS),Fourier-transformed infrared spectroscopy(FT-IR),photoluminescence(PL),and UV-Vis diffused reflectance spectroscopy(DRS).XRD results revealed the existence of a monoclinic scheelite structure in both the unmodified and the modified samples.The TX100 played a crucial role to control the cuboid-like shape morphology of BiVO_4.The DRS results showed that the as-prepared cuboid BiVO_4 possessed enhanced visible light absorption range compared with that of the unmodified BiVO_4.The photocatalytic activity was evaluated via indigo carmine(IC) degradation under visible light irradiation.The modified BiVO_4 showed higher photocatalytic efficiency than the unmodified BiVO_4 and the commercial P25-TiO_2 which could be ascribed to the better charge separation efficiency.
