Preparation and study on the photocatalytic mechanism of ZnFe₂O₄/Ag₃PO₄composite photocatalysts

In order to solve the disadvantages of most of the photocatalyst, ZnFe₂O₄is chosen as the magnetic material and prepared ZnFe₂O₄/Ag₃PO₄composite photocatalysts. ZnFe₂O₄is prepared by hydrothermal method, the ZnFe₂O₄/Ag₃PO₄is prepared by precipitation method, which supported Ag₃PO₄on the surface of ZnFe₂O₄. The synthesis method of ZnFe₂O₄/Ag₃PO₄not only simplifies the preparation process, but also improves the photocatalytic activity by suppressing the electron-hole recombination. These methods have important significance for the function alization and stability of photocatalytic materials. Moreover, the ZnFe₂O₄/Ag₃PO₄is characterised by a series of testing means, such as SEM, XRD and EDS, etc. At the same time, this work realizes the effective control of environmental pollutants and lay the foundation for the research of organic pollution remove.
