Ternary chalcogenide semiconductor, cadmium indium sulfide (CdInS), was prepared by a simple solvothermal method using ethylene glycol as a solvent, as well as indium chloride tetrahydrate (InCl4HO), cadmium nitrate tetrahydrate [Cd(NO)4HO], and thiacetamide (TAA) as precursors. The resulted sample was subject to a series of characterizations. It is the first time to use CdInS sample as a visible light-driven photocatalyst for simultaneous selective redox transformation of organic aromatic compounds. The results indicate that the as-synthesized CdInS photocatalyst not only has excellent photocatalytic performance compared with pure InS 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 CdInS photocatalyst and provide new insights for selective transformations of organic compounds.
采用简单的溶剂热法，以乙二醇为溶剂，四水合氯化铟（InCl₄·H₂O）、四水合硝酸镉[Cd(NO₃)₂·4H₂O]和硫代乙酰胺（TAA）为前驱体，制备了三元硫属化物半导体硫化镉铟（CdInS）。对所得样品进行了一系列表征。首次将CdInS样品用作可见光驱动的光催化剂，用于有机芳香化合物的同时选择性氧化还原转化。结果表明，所合成的CdInS光催化剂不仅在氧气环境中对芳香醇的选择性氧化方面，与纯InS和CdS相比具有优异的光催化性能，而且在氮气气氛下也表现出高光催化氧化还原活性。提出了耦合体系中光催化氧化还原反应的可能机理。希望我们目前的工作能够拓展CdInS光催化剂的应用，并为有机化合物的选择性转化提供新的见解。
