A kind of preparation method of Z form bismuth-based photocatalyst |
abstract |
The invention relates to a preparation method of a Z-form bismuth-based photocatalyst, and belongs to the technical field of nanomaterials. By adding the bismuth salt and the iodine source into the solvent to dissolve completely or disperse uniformly, a reaction solution containing the precursor of bismuth iodide is obtained after sufficient reaction; the composite phase substance and the reducing agent are added to the reaction solution prepared in step (1) to react , obtain a reaction solution with a reducing chemical atmosphere, containing bismuth iodide-composite phase precursor; heat the reaction solution obtained in step (2) with a solvent, and separate and dry the reaction solution after the solvent heat treatment to obtain the catalyst. . The catalyst can retain a high redox potential on the basis of effectively separating electron-hole pairs; compared with the heterojunction structure obtained without adding a reducing agent, it has the ability to complete the photocatalytic degradation of organic compounds such as rhodamine B faster. Effect. |
