Ce/BiVO4 nanocomposites photocatalyst was synthesized by direct feeding\nmicrowave synthesis method, using bismuth nitrate (Bi (NO3)3·5H2O), cerium\nnitrate hexahydrate (Ce (NO3)3·6H2O) and ammonium metavanadate (NH4VO3)\nas raw material and sodium dodecyl sulfate (SDS) as surfactant. The X-ray\ndiffractometer (XRD) and the scanning electron microscopy (SEM) technology\nwere used to characterize the Ce/BiVO4 nanocomposites. We investigated\nthe photocatalytic activity of the as-prepared photocatalyst, and methyl\norange was used as organic pollutant. The results show that the Ce/BiVO4\nnanocomposite was a good photocatalyst under visible light. In 100 ml of 5\nmg/L methylene orange solution, when the catalyst calcined at 673 K was 0.1\ng, hydrogen peroxide was 0.5 ml, pH was 2.0, and the degradation ratio of catalyst\nfor methylene orange reached 90.26% within 70 min.
