Preparation of Bi2S3 Composite BiOCl Photocatalyst Based on Hydrothermal Synthesis Method
In order to obtain new and effective photocatalysts to meet the requirements of modern sustainable development,a preparation method of Bi2S3 composite BiOCl photocatalyst based on hydrothermal synthesis method is proposed in the experiment.The characterization characteristics of the photocatalyst were analyzed using techniques such as X-ray diffraction(XRD)and scanning electron microscopy(SEM).The results showed that the prepared Bi2S3 composite BiOCl photocatalyst formed a good heterojunction inside,and no diffraction peaks of other crystal phases were found.The position and intensity of the diffraction peaks did not change significantly.However,the absorption edge of the composite material shows a significant position redshift relative to BiOCl.The above results indicate that hydrothermal synthesis can be used to prepare new composite materials and improve the utilization efficiency and catalytic activity of photocatalysts.
