The invention belongs to the technical field of photocatalytic materials, and relates to a preparation method and application of a metal organic framework catalyst with a torsional structure, wherein the preparation method comprises the following steps: is ligand H with twisted structure 3 Twisted and copper nitrate are prepared into the metal organic framework catalyst with a Twisted structure by a solvothermal method, and the synthetic route is as follows: h 3 Twisted+Cu(NO 3 ) 2 ·H 2 O → Cu-Twisted; the Cu-Twisted metal-organic framework catalyst with the Twisted structure has the advantages that due to the controlled electron transfer process, the reserved divalent copper node exerts an inner shell layer electron regulation effect on a substrate, the selective chlorination trifluoromethyl bifunctional reaction of electron-deficient olefin is realized, and the homogeneous catalyst does not show chemical zone selectivity in the reaction. |
