摘要

声光催化被描述为光催化和声催化两个单独过程的结合。事实证明,它在降解废水中的溶解污染物以及细菌消毒应用方面非常有前景。它消除了在每种单独技术中观察到的一些主要缺点,如高成本、缓慢的活性和延长的反应时间。该综述对声光催化反应机理以及纳米结构催化剂和工艺改性技术对声光催化剂性能的影响进行了关键分析。已经讨论了上述工艺、反应器设计和电能消耗之间的协同效应,因为它们在实际应用中(如实际的工业或城市污水处理厂)实施这一新技术时具有重要意义。综述了声光催化在细菌消毒灭活中的应用。此外,我们进一步建议改进,将这项技术从实验室规模推广到大规模应用。我们希望这篇最新的综述将推动该领域未来的研究,并推动该技术的广泛采用和商业化。

Sonophotocatalysis with Photoactive Nanomaterials for Wastewater Treatment and Bacteria Disinfection

Sonophotocatalysis is described as a combination of two individual processes of photocatalysis and sonocatalysis. It has proven to be highly promising in degrading dissolved contaminants in wastewaters as well as bacteria disinfection applications. It eliminates some of the main disadvantages observed in each individual technique such as high costs, sluggish activity, and prolonged reaction times. The review has accomplished a critical analysis of sonophotocatalytic reaction mechanisms and the effect of the nanostructured catalyst and process modification techniques on the sonophotocatalytic performance. The synergistic effect between the mentioned processes, reactor design, and the electrical energy consumption has been discussed due to their importance when implementing this novel technology in practical applications, such as real industrial or municipal wastewater treatment plants. The utilization of sonophotocatalysis in disinfection and inactivation of bacteria has also been reviewed. In addition, we further suggest improvements to promote this technology from the lab-scale to large-scale applications. We hope this up-to-date review will advance future research in this field and push this technology toward widespread adoption and commercialization.
