目前, 高价铁物种 (high-valent iron species, HVIS) 在基于铁基催化材料诱导的高级氧化工艺 (advanced oxidation processes, AOPs) 处理各种污染水体方面展现出较好的应用前景. 然而, 已有的研究对 AOPs 中 HVIS 的产生、控制、识别的刻画还不够精细、明确, 且HVIS 对消除污染物的贡献程度和反应机制也缺乏条理性分析和综合性总结, 这对依靠高活性HVIS 的 AOPs 在实际应用中保持高性能长效修复效果会产生一定影响和限制. 因此, 重点讨论了基于铁基催化材料下 HVIS 的产生、控制, 获取其主控影响因素、HVIS 的识别手段及其与典型污染物反应机制, 以期为基于 HVIS 的 AOPs 在未来发展应用中提供理论支撑与参考.

High-valent iron species (HVIS) have good application prospects in iron-based catalytic-induced advanced oxidation processes (AOPs) for various water treatments. How-ever, existing studies lack clarity regarding the generation, control, and identification of HVIS in AOPs. Additionally, there is a dearth of organized analyses and summaries of the degree of contribution of HVIS to pollutant removal and the underlying reaction mechanisms. These limitations can potentially hinder the practical application of AOPs that rely on high-activity HVIS to achieve high-performance long-term remediation. Therefore, this study focused on the generation, control, and main influencing factors of HVIS by iron-based catalysis, as well as their identification methods and reaction mechanisms with typical pollutants. The aim was to provide theoretical support and references for the future development and application of AOPs based on HVIS.
