Abstract

Using Ni(NO3)2•6H2O, Bi(NO3)3•5H2O and NH4VO3 as raw materials, Ni-doped BiVO4 photocatalysts with monoclinic scheelite were prepared by a low-temperature grinding method. The physical and optical properties of the samples were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) and UV-VIS diffuse reflectance spectroscopy (DRS), and the chemical bond of the samples was analyzed by Infrared spectroscopy (FT-IR). The Methyl Orange (MO) was simulated as the sewage under the condition of visible light for studying the influence of the amount of photocatalyst and the illumination time. The results showed that the visible-light absorption scope of BiVO4 was broadened by doping Ni and the catalytic effect was enhanced comparing with the pure BiVO4. The degradation rate of as-prepared samples was up to 90% with 10mg and 20mg Ni and photocatalytic time of 90 min.
