The invention discloses a Fe2O3 - MXenes composite catalyst, a preparation method and application thereof, and belongs to the technical field of water treatment. It first intercalates Ti 3 C 2 T x MXenes with an intercalating agent; and then mixes and reacts the intercalated Ti 3 C 2 T x MXenes with iron ion salts and organic ligands, which can react with Fe 3 + Coordinate to form Fe-MOF, and the intermediate MOF-MXenes is obtained after the mixed reaction; finally, the intermediate MOF-MXenes is carbonized to obtain the Fe 2 O 3 -MXenes composite catalyst. The invention improves the problems of easy agglomeration, poor electron transfer performance and poor stability of the ferric oxide prepared by the traditional method, can well activate persulfate to degrade tetracycline in wastewater, has high efficiency, high use value and easy catalyst The advantages of recycling, etc., have great application prospects. |
