Abstract

Using Bi(NO3)3•5H2O, NH4VO3 and Zn(NO3)2•6H2O as raw material, Zn-doped BiVO4 photocatalysts were successfully prepared by a low-temperature grinding synthesis. And the samples were characterized by X-ray diffraction (XRD), Infrared spectroscopy (FT-IR) and UV-Vis diffuse reflectance spectroscopy (DRS). The Methyl Orange (MO) was simulated as the sewage under the visible light to study the influence of the illumination time and the amount of photocatalyst. The visible-light absorption scope of BiVO4 was broaden by doping Zn2+, the UV-Visible absorption edge was slightly red shifted and the band gap was narrowed comparing with the pure BiVO4. It was found that the catalytic effect of the Zn-doped catalysts was enhanced under the visible-light irradiation. The cause of enhanced catalytic effect has also been analyzed and discussed in the article.
