Facile Solid State Method Route Synthesis and Enhance Visible Light Activities of BiVO₄ by Doping Co

Abstract:

Using NH₄VO₃, Bi (NO₃)₃•5H₂O and Co (NO₃)₂•6H₂O as raw materials, Co doped BiVO₄ (Co/BiVO₄) photocatalysts were successfully prepared by solid state method. And the photo catalytic properties were test in this work. Crystal structures of these samples were characterized by X-ray diffraction (XRD). The Methyl Orange (MO) was simulated as the sewage under the visible light to explorer the influence of the illumination time and the mass of photocatalyst. The visible-light absorption spectrum of BiVO₄ was broadening with doping Co. It was found that the Co/BiVO₄ had higher photocatalytic activity than pure BiVO₄ .The reason of enhanced catalytic effect also had been analyzed and discussed in the article.
