Fenton-like advanced oxidation processes (AOPs) are commonly used to eliminate recalcitrant organic pollutants as they produce highly reactive oxygen species through the reactions between the catalysts and oxidants. Recently, considerable attention has been directed towards shell-structured Fenton-like catalysts that offer high stability, maximum utilization of active sites, and exceptional catalytic performance. In this review, we have introduced the concept of several typical shell-forming architectures (e.g., hollow structure, core-shell structure, yolk-shell structure, particle-in-tube structure, and multi-shelled structure), elucidating their role in promoting Fenton-like reaction catalysis through the nanoconfinement mechanism. In each aspect, the correlation between the shell-induced effects and the Fenton-like catalytic performance is highlighted. Finally, future challenges and opportunities for the development of shell-structured Fenton-like catalysts towards AOPs are presented, offering bright practical application prospects.
类芬顿高级氧化过程（AOPs）通常用于消除难降解有机污染物，因为它们通过催化剂与氧化剂之间的反应产生高活性氧物种。最近，具有壳结构的类芬顿催化剂受到了广泛关注，这类催化剂具有高稳定性、活性位点的最大利用率和出色的催化性能。在这篇综述中，我们介绍了几种典型的壳层形成结构（如中空结构、核壳结构、蛋黄壳结构、管中颗粒结构和多壳结构）的概念，阐明了它们通过纳米限域机制在促进类芬顿反应催化中的作用。在各个方面，都强调了壳层诱导效应与类芬顿催化性能之间的相关性。最后，提出了壳结构类芬顿催化剂在AOPs发展方面未来面临的挑战和机遇，展现出光明的实际应用前景。
