This research aims to prepare Bi2WO6-based photocatalyst and explore its photocatalytic properties. Firstly, the basic properties of Bi2WO6 were introduced, and its applications in environmental pollution control, solar energy utilization were summarized, and the shortcomings of existing research were analyzed, which provided a theoretical basis and research ideas for this study. On this basis, a new preparation method was proposed, namely, the hydrothermal method combined with the sol-gel method. By adjusting the hydrothermal conditions, the Bi2WO6-based photocatalyst with high purity, small particle size, and high photocatalytic activity was obtained, and its performance was tested in the degradation of acetic acid photocatalysis and rhodamine B(RhB). The experimental results showed that the prepared Bi2WO6-based photocatalyst has extremely high catalytic activity and stability, which is suitable for application in environmental pollution control and other fields.精品文档---下载后可任意编辑Keywords: Bi2WO6; photocatalyst; preparation method; photocatalytic properties
