ABSTRACT

In the last decade, a considerable body of literature has been devoted to advanced oxidation processes encompassed peroxy-sulfur species owing to their capacity to generate highly active radicals. These species fulfill two main objectives in AOPs: act as electron-scavengers and give rise to sulfate radicals, which collectively facilitate the oxidation of organic pollutants. This review provides data on the recent strategies and practices aimed to enhance the photocatalytic performance of TiO₂ where persulfate/peroxymonosulfate species are supplemented. The mechanism of persulfate activation, direct and interactive effects on the photoactivity of TiO₂ nanostructures, and subsequent degradation efficiencies of agrochemicals, dyes, pharmaceuticals, petrochemicals, and pathogenic microorganisms were studied and thoroughly discussed. The data on several titania-based nanostructures, the best operational conditions, and the removal outputs in the presence of oxidants and electron acceptors, in particular, persulfate ions are summarized, depicted, and tabulated. As per reviewed literature, titania-persulfate integration can effectively address the environmental implications of organic pollutants.

摘要

在过去十年中，大量文献致力于高级氧化过程，包括过氧硫物质，因为它们能够产生高活性自由基。这些物种在 AOP 中实现两个主要目标：充当电子清除剂并产生硫酸根，共同促进有机污染物的氧化。这篇综述提供了有关旨在增强 TiO ₂的光催化性能的最新策略和实践的数据，其中补充了过硫酸盐/过氧单硫酸盐物质。过硫酸盐活化机制、对TiO _{2光活性的直接和交互作用}对农用化学品、染料、药物、石化产品和病原微生物的纳米结构和随后的降解效率进行了研究和深入讨论。总结、描述和列出了几种二氧化钛纳米结构的数据、最佳操作条件以及在存在氧化剂和电子受体（尤其是过硫酸根离子）的情况下的去除输出。根据评论文献，二氧化钛-过硫酸盐整合可以有效解决有机污染物对环境的影响。
