Title:
FE2O3-MXENE COMPOSITE CATALYST, AND PREPARATION METHOD THEREFOR AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2023/222143
Kind Code:
A1
Abstract:
The invention discloses a Fe2O3-MXene composite catalyst, and a preparation method therefor and the use thereof, which belong to the technical field of water treatment. The method comprises: firstly intercalating a Ti3C2Tx-MXene using an intercalator; then mixing the intercalated Ti3C2Tx-MXene with an iron ion salt and an organic ligand for a reaction, wherein the organic ligand can be coordinated with Fe3+ to form Fe-MOF, and an intermediate MOF-MXene is obtained after the mixing and reaction; and finally carbonizing the intermediate MOF-MXene to obtain a Fe2O3-MXene composite catalyst. In the present invention, the problems of ferric oxide prepared by a traditional method being prone to agglomeration and having a poor electron transfer performance and a poor stability are solved, tetracycline in persulfate degradation wastewater can be fully activated, and the method has the advantages of a high efficiency, a high use value, ease of catalyst recovery, etc., and has great application prospects.
