超声协同纳米TiO2光催化降解水中苯酚机理的研究

本文考察了声光催化技术降解水中苯酚的降解效率，测定了超声波联合光催化降解苯酚的主要中间产物，初步探讨了声光催化降解苯酚的反应机理。实验结果表明：超声波与光催化之间存在协同效应；光催化与声光催化降解苯酚的反应历程和产物基本一致。这两个反应的中间产物都是苯醌、邻苯二酚和对苯二酚；最终产物是水和二氧化碳。

Study on the Mechanism of Sonophotocatalytic Degradation of Phenol in Water

In this paper,the combination of ultrasound (US) and photocatalysis has been used to degrade phenol in an aqueous solution.The reaction process and the degradation mechanism were discussed.It was found that:there was synergistic effect between the two methods were the reaction process and degradation products of photocatalysis and sonophotocatalytic were almost the same.Their intermediates included benzoquinone,adjacent diphenol and hydroquinone.The final products were carbon dioxide and water.
