Solvothermal synthesis of CdIn₂S₄ photocatalyst for selective photosynthesis of organic aromatic compounds under visible light.

ABSTRACT: Ternary chalcogenide semiconductor, cadmium indium sulfide (CdIn₂S₄), was prepared by a simple solvothermal method using ethylene glycol as a solvent, as well as indium chloride tetrahydrate (InCl₃^.4H₂O), cadmium nitrate tetrahydrate [Cd(NO₃)₂^.4H₂O], and thiacetamide (TAA) as precursors. The resulted sample was subject to a series of characterizations. It is the first time to use CdIn₂S₄ sample as a visible light-driven photocatalyst for simultaneous selective redox transformation of organic aromatic compounds. The results indicate that the as-synthesized CdIn₂S₄ photocatalyst not only has excellent photocatalytic performance compared with pure In₂S₃ and CdS for the selective oxidation of aromatic alcohols in an oxygen environment, but also shows high photocatalytic redox activities under nitrogen atmosphere. A possible mechanism for the photocatalytic redox reaction in the coupled system was proposed. It is hoped that our current work could extend the applications of CdIn₂S₄ photocatalyst and provide new insights for selective transformations of organic compounds.
