| Abstract: | In this paper, BiVO4 monomer was synthesized by hydrothermal method, and modified by polyvinyl alcohol to a porous ceramic carrier prepared by organic foam impregnation method to obtain a BiVO4/porous ceramic composite photocatalyst, and the composition and morphology of the catalyst were characterized by XRD, SEM and other instruments. The results show that the catalyst prepared in this experiment has excellent modification effect, has a low band gap, and improves the utilization rate of sunlight to a certain extent. In addition, the catalyst has high porosity and specific surface area, good wettability to liquid, and can effectively contact with pollutants in liquid, which improves the degradation efficiency. The photocatalytic activity of the catalyst was analyzed by the degradation of methylene blue (MB) solution by using this catalyst. The data showed that when the loading of BiVO4 was 20%, the degradation efficiency of BiVO4/porous ceramics for methylene blue solution within 2.5 h under visible light was as high as 80.83%. Cycling experiments show that BiVO4/porous ceramics have good photocatalytic performance stability, which is due to the efficient recovery of porous ceramic carriers. Therefore, this study is of great significance for the efficient application of photocatalytic technology. |
