Visible-light-driven organic oxidation over CdS-doped metal–organic frameworks

Abstract

In this research, we synthesized CdS nanoparticle-doped metal–organic frameworks (CdS@DUT-52) with different contents using a solvothermal method. CdS@DUT-52 possesses strong light absorption ability and effective electron–hole separation properties, which was proved by performing UV-vis spectroscopy and photoelectrochemical testing. It was used to trigger the photooxidation of amines, sulfides, and alcohols to produce the corresponding imines, sulfoxides, and aldehydes in the presence of air or oxygen, exhibiting considerable yields of products under visible light irradiation compared with a single component.
