有机磷酸盐已被确定为废水中的一组新的污染物，具有显著的负面人类健康影响。由于它们在流域、土壤和食物链中的持久性，它们在废水处理过程中和释放之前的降解引起了人们的极大兴趣。高级氧化工艺能够以高转化率和快速动力学降解有机磷酸酯。光-芬顿和光-芬顿类工艺利用光源来引发芬顿反应并产生反应传播所需的活性氧物质。虽然均相催化剂已被广泛研究，但非均相催化剂由于其易于使用、分离和回收而正在出现。本文综述了近年来非均相类光Fenton法降解有机磷的研究进展，并与均相法进行了比较，提出了合理设计光催化剂的必要性和今后的研究方向。包括利用代表真实世界组成复杂性的废水进料以及提供分子-水平的催化过程的见解，以更好地了解这些催化剂的局限性。
Organophosphates have been identified as an emerging group of contaminants in wastewater with significant negative human health effects. Due to their persistence in the watershed, soil, and the food chain, their degradation during wastewater treatment and before the release has garnered significant interest. Advanced oxidation processes enable the degradation of organophosphates with high conversion and fast kinetics. Photo-Fenton and photo-Fenton-like processes utilize a light source to initiate the Fenton reaction and produce reactive oxygen species that are required for the reaction propagation. While homogeneous catalysts have been studied extensively, heterogeneous catalysts are emerging due to their ease of use, separation, and recycling. This review provides a summary of the current progress made in the field of organophosphate degradation using a heterogeneous photo-Fenton-like process when compared to the homogeneous process and highlights the need for the rational photocatalyst design as well as suggests future directions of research, including utilizing wastewater feeds that represent real-world compositional complexity as well as providing molecular-level catalytic process insights to better understand limitations of these catalysts.
