研究目的
To develop a novel hybridizing engineering (HE) strategy for the preparation of carbon quantum dot (CQD)-hybridized (nBu4N)4W10O32 (TBADT) catalysts with enhanced visible-light-catalytic oxidation performance.
研究成果
The hybridizing of CQD significantly enhances the photo-catalytic performance of TBADT in visible light-triggered selective oxidation of organic compounds with O2. The optimized hybrid containing 3% CQD shows much higher photo-catalytic activity than pure TBADT, with the additive 2 M HCl further enhancing the hybridization effects.
研究不足
The study is limited to the visible light-triggered selective oxidation of specific organic compounds and the use of acetonitrile as the solvent. The effect of other solvents or light sources was not explored.
1：Experimental Design and Method Selection:
The study involves the hydrothermal treatment of CQD with TBABr solution to form TBA+ micelle-encapsulated CQD, which combines with W10O32 anion to produce the target catalyst.
2：Sample Selection and Data Sources:
Sodium tungstate, tetrabutylammonium bromide, ethylenediamine, citric acid, and other chemicals were used.
3：List of Experimental Equipment and Materials:
Te?on-lined autoclave, UV–vis spectrophotometer, fluorescence spectrophotometer, electrochemical analyzer, etc.
4：Experimental Procedures and Operational Workflow:
The synthesis of CQD-hybridized TBADT catalysts and their characterization using XPS, UV–vis, PL, and CV techniques.
5：Data Analysis Methods:
The photo-catalytic performances were assessed using the oxidation of cyclohexane with molecular oxygen (O2) in MeCN under visible light illumination.
