Microwave Synthesis of Ce/BiVO4 Nanocomposites Photocatalyst and Their Photocatalytic Properties
Abstract: Ce/BiVO4 nanocomposites photocatalyst was synthesized by direct feeding microwave synthesis method, using bismuth nitrate (Bi (NO3)3·5H2O), cerium nitrate hexahydrate (Ce (NO3)3·6H2O) and ammonium metavanadate (NH4VO3) as raw material and sodium dodecyl sulfate (SDS) as surfactant. The X-ray diffractometer (XRD) and the scanning electron microscopy (SEM) technology were used to characterize the Ce/BiVO4 nanocomposites. We investigated the photocatalytic activity of the as-prepared photocatalyst, and methyl orange was used as organic pollutant. The results show that the Ce/BiVO4 nanocomposite was a good photocatalyst under visible light. In 100 ml of 5 mg/L methylene orange solution, when the catalyst calcined at 673 K was 0.1 g, hydrogen peroxide was 0.5 ml, pH was 2.0, and the degradation ratio of catalyst for methylene orange reached 90.26% within 70 min.
