金属有机骨架（MOF）及其衍生物因其超高的孔隙率、可调的性能和优异的配位能力而在光/电催化领域备受关注。调控MOFs的价电子结构和配位环境是增强其内在催化性能的有效途径。具有 4f 轨道占据的稀土 (RE) 元素提供了引发电子重排、加速带电载流子传输并协同催化剂表面吸附的机会。因此，RE与MOF的集成可以优化其电子结构和配位环境，从而增强催化性能。本文总结并讨论了当前使用稀土修饰的 MOF 及其衍生物进行光/电催化的研究进展。首先介绍了RE在MOF改性中的理论优势，重点介绍了4f轨道占据和RE离子有机配位配体的作用。然后系统地讨论了RE修饰的MOFs及其衍生物在光/电催化中的应用。最后，还讨论了 RE-MOF 的研究挑战、未来机遇和前景。

Rare-Earth–Modified Metal–Organic Frameworks and Derivatives for Photo/Electrocatalysis

Metal–organic frameworks (MOFs) and their derivatives have attracted much attention in the field of photo/electrocatalysis owing to their ultrahigh porosity, tunable properties, and superior coordination ability. Regulating the valence electronic structure and coordination environment of MOFs is an effective way to enhance their intrinsic catalytic performance. Rare earth (RE) elements with 4f orbital occupancy provide an opportunity to evoke electron rearrangement, accelerate charged carrier transport, and synergize the surface adsorption of catalysts. Therefore, the integration of RE with MOFs makes it possible to optimize their electronic structure and coordination environment, resulting in enhanced catalytic performance. In this review, progress in current research on the use of RE-modified MOFs and their derivatives for photo/electrocatalysis is summarized and discussed. First, the theoretical advantages of RE in MOF modification are introduced, with a focus on the roles of 4f orbital occupancy and RE ion organic coordination ligands. Then, the application of RE-modified MOFs and their derivatives in photo/electrocatalysis is systematically discussed. Finally, research challenges, future opportunities, and prospects for RE-MOFs are also discussed.
