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.
金属有机框架材料（MOFs）及其衍生物因其超高孔隙率、可调控性能和卓越的配位能力，在光催化/电催化领域备受关注。调控MOFs的价电子结构和配位环境是提高其本征催化性能的有效途径。具有4f轨道占据的稀土（RE）元素为引发电子重排、加速载流子传输以及协同催化剂的表面吸附提供了契机。因此，将稀土与MOFs整合能够优化其电子结构和配位环境，从而提高催化性能。在本综述中，总结并讨论了当前关于稀土修饰的MOFs及其衍生物用于光催化/电催化研究的进展。首先，介绍了稀土在MOF修饰中的理论优势，重点关注4f轨道占据和稀土离子有机配位配体的作用。然后，系统讨论了稀土修饰的MOFs及其衍生物在光催化/电催化中的应用。最后，还讨论了稀土-金属有机框架材料（RE-MOFs）的研究挑战、未来机遇和前景。
