| abstract |
The invention relates to a preparation method of a novel visible light catalyst, in particular to a preparation method of a BiOBr x I 1-x /MXene composite catalyst. The present invention adopts a liquid phase etching method (HF and HCl+LiF etching method) Synthesize MXene, and then prepare a series of BiOBr x I 1-x / MXene through a solvothermal method. Benefiting from its advantages such as larger specific surface area, more active sites, and faster photogenerated carrier transfer, it can greatly improve its efficiency and stability in photocatalytic degradation of organic pollutants, and the preparation method is simple. Moderately conducive to industrial production. |
