摘要：

A visible-light-driven photocatalyst-magnetic BiVO4-was synthesized by an aqueous deposition method and characterized by XRD, SEM, UV-Vis DRS and low temperature nitrogen adsorption-desorption. The results show that magnetic BiVO4 photocatalysts have monoclinic scheelite structure and increase visible-light absorption. The BET specific surface area is a little lower than that of BiVO4. The photocatalytic activity of magnetic BiVO4 photocatalysts was investigated in methylene blue solution under visible-light irradiation. The photocatalytic activity of magnetic BiVO4 photocatalysts is better than that of the pure one because of the reduction of E-g, the enhancement of absorption in visible light region and increasement of adsorption of methylene blue. The increased adsorption of methylene blue is explained in terms of the lower isoelectric point of magnetic BiVO4 than pure BiVO4.
