With the ever-growing water pollution issues, advanced oxidation processes (AOPs) have received growing attention due to their high efficiency in the removal of refractory organic pollutants. Transition metal sulfides (TMSs), with excellent optical, electrical, and catalytical performance, are of great interest as heterogeneous catalysts. These TMSs-based heterogeneous catalysts have been demonstrated to becapable and adaptable in water purification through advanced oxidation processes. The aim of this review is to conduct an exhaustive analysis and summary of recent progress in the application of TMSs-based AOPs for water decontamination. Firstly, the commonly used tuning strategies for TMSs-based catalysts are concisely introduced, including artificial size and shape control, composition control, doping, and heterostructure manufacturing. Then, a comprehensive overview of the current state-of-the-art progress on TMSs-based AOPs (i.e., Fenton-like oxidation, photocatalytic oxidation, and electro chemical oxidation processes) for wastewater treatment is discussed in detail, with an emphasis on their catalytic performance and involved mechanism. In addition, influencing factors of water chemistry, namely, pH, temperature, dissolved oxygen, inorganic species, and natural organic matter on the catalytic performance of established AOPs are analyzed. Furthermore, the reusability and stability of TMSs-based catalysts in these AOPs are also outlined. Finally, current challenges and future perspectives related to TMSs-based catalysts and their applications for AOPs wastewater treatment are proposed. It is expected that this review would shed some light on the future development of TMSs-based AOPs towards water purification.
随着水污染问题的日益严重，由于其在去除难降解有机污染物方面的高效性，高级氧化工艺（AOPs）受到了越来越多的关注。过渡金属硫化物（TMSs）具有优异的光学、电学和催化性能，作为多相催化剂具有很大的吸引力。这些基于 TMSs 的多相催化剂已被证明能够且适应于通过高级氧化工艺进行水净化。本综述的目的是对 TMSs 基 AOPs 在水净化中的应用的最新进展进行全面分析和总结。首先，简要介绍了基于 TMSs 的催化剂的常用调谐策略，包括人工尺寸和形状控制、组成控制、掺杂和异质结构制造。然后，详细讨论了基于 TMSs 的 AOPs（即类芬顿氧化、光催化氧化和电化学氧化过程）在废水处理方面的最新进展，重点介绍了它们的催化性能和所涉及的机制。此外，还分析了水化学的影响因素，即 pH 值、温度、溶解氧、无机物种和天然有机物对已建立的 AOPs 的催化性能的影响。此外，还概述了 TMSs 基催化剂在这些 AOPs 中的可重复使用性和稳定性。最后，提出了与 TMSs 基催化剂及其在 AOPs 废水处理中的应用相关的当前挑战和未来展望。希望本综述能为 TMSs 基 AOPs 未来在水净化方面的发展提供一些启示。
