Photocatalytic Activity of Gd³⁺ and Sm³⁺ Co-Doped BiVO₄Powders Prepared by Chemical Precipitation Process

Abstract:

Pure BiVO₄, single doped and co-doped BiVO₄ have been prepared by chemical precipitation method and characterized by the techniques such as XRD and SEM/EDAX. The photocatalytic degradation of methylene blue (MB) in aqueous solution was used as a probe reaction to evaluate pure BiVO₄, single doped BiVO₄and co-doped BiVO₄ photocatalytic activity. The results show that doping of single doped and co-doped significantly enhance the photocatalytic activity of BiVO₄. When the 0.1%Gd³⁺ and 0.2%Sm co-doped, the BiVO₄ degradation rate reaches 91%.
