3D flower-shaped Z-type heterojunction photoelectric catalyst Zn3In2S6 (at) Bi2WO6 as well as preparation method and application thereof

The invention relates to a 3D flower-shaped Z-type heterojunction photoelectric catalyst Zn3In2S6 (at) Bi2WO6 as well as a preparation method and application thereof. According to the technical scheme, the preparation method comprises the following steps: dissolving Bi (NO3) 3.5 H2O into a mixed solution of deionized water and glacial acetic acid, uniformly mixing, adding an aqueous solution of Na2WO4. 2H2O, adding Zn3In2S6 into the obtained mixed solution, stirring for 1 hour, transferring into a high-pressure kettle for hydrothermal reaction, and washing and drying a product to obtain Zn3In2S6 and Bi2WO6. The prepared photoelectric catalyst Zn3In2S6 and Bi2WO6 is used for efficiently and rapidly producing H2O2 and is beneficial to promoting the application of a photoelectric catalysis technology in the field of production of clean energy. 本发明涉及3D花状Z型异质结光电催化剂Zn3In2S6@Bi2WO6及其制备方法和应用。采用的技术方案是：将Bi(NO3)3·5H2O溶于去离子水和冰醋酸的混合溶液中，混合均匀后，加入Na2WO4·2H2O的水溶液，然后于所得混合溶液中加入Zn3In2S6，搅拌1h，转移至高压釜中进行水热反应，产物洗涤，干燥，得到Zn3In2S6@Bi2W
