Abstract

Using the Bi(NO3)3•5H2O, NH4VO3 and 50% Mn(NO3)2 solution as raw materials, the novel Mn2+-doped BiVO4 photocatalysts was successfully prepared by a low-temperature grinding synthesis. And characterized by X-ray diffraction(XRD) and scanning electron microscope(SEM). The Methyl Orange (MO) was simulated as the degradation material under the visible light for studying the influence of the amount of photocatalyst and the illumination time. The visible-light absorption scope of BiVO4 was broadened by doping Mn2+, the UV-Visible absorption edge was slightly red shifted and the band gap got narrowed comparing with the pure BiVO4. The results indict that the photocatalytic activities of Mn2+/BiVO4 were improved comparing with the pure BiVO4. The possible reason of enhanced photocatalytic activities was discussed.
