As a new class of water treatment technologies, redox-based advanced oxidation processes (AOP) involving peroxymonosulfate (PMS) activation show wide application prospect in the water treatment. Accordingly, cobalt-doped materials have proven to be some of the most effective and efficient heterogeneous catalysts for activating PMS to degrade a variety of recalcitrant organic pollutants. In this critical review, cobalt-doped catalysts are reasonably classified according to the types of solid substrates used, and their catalytic performances in the degradation of various organic pollutants in wastewater are summarized. The catalytic mechanisms of cobalt-doped catalysts for activating PMS are discussed in detail, where the effect of the substrate on the overall catalytic activity is emphasized. In addition, we also discuss the durability and cobalt leaching of the cobalt-doped catalysts for the degradation of organic pollutants. This review shows that cobalt-doped catalysts have promising potential in water treatment based on the promotion or synergistic effect of the substrate, reduced cobalt dosage, and their stable structure. It also provides a perspective on future research on cobalt-based catalyst/PMS systems in practical environmental cleanup.

利用钴掺杂材料作为多相催化剂激活过硫酸盐降解有机污染物：批判性评论
作为一种新型的水处理技术，涉及过硫酸盐（PMS）活化的氧化还原基高级氧化工艺（AOP）在水处理中具有广泛的应用前景。因此，钴掺杂材料已被证明是一些最有效和最有效的多相催化剂，用于激活 PMS 以降解各种顽固的有机污染物。在这篇批判性评论中，根据所使用的固体基质的类型对钴掺杂催化剂进行了合理的分类，并总结了它们在废水中降解各种有机污染物的催化性能。详细讨论了钴掺杂催化剂活化 PMS 的催化机制，其中强调了底物对整体催化活性的影响。此外，我们还讨论了用于降解有机污染物的钴掺杂催化剂的耐久性和钴浸出。该综述表明，基于底物的促进或协同作用、减少钴用量及其稳定的结构，钴掺杂催化剂在水处理中具有广阔的潜力。它还为未来在实际环境清理中钴基催化剂/PMS 系统的研究提供了一个视角。
