摘要
Carboxylic acid is one of the most crucial and widely used organic chemicals in daily human life activities. Hence preparation of this important chemical was performed under the application of the highly selective photo-catalysts through oxidation of alcohols to carboxylic acids. Herein, we have designed and disclosed a binary NH2-MIL-125(Ti)/ NaBr) catalyst system to realize the effective transformation of alcohols into carboxylic acids under visible light irradiation. Hence, derivatives of benzyl alcohol containing either electron withdrawing and donating groups as well as aliphatic primary alcohols were effectively converted into the corresponding carboxylic acids. Based on our findings, NH2-MIL-125(Ti) based photocatalytic system has shown efficient and highly selective activities for oxidation of alcohol especially the in-situ conversion of co-catalyst NaBr into the corresponding free radical can enhance the alcohol oxidation performance of the catalytic system.
