摘要:

金属有机框架材料(MOFs)因其高比表面积、可调孔径结构和多功能性, 在电催化领域展现出广阔的应用前景. 然而, 传统MOFs多采用单核金属离子构建, 存在活性位点有限、电子传输效率低等问题, 限制了其催化性能的进一步提升. 多核MOFs通过引入金属团簇作为次级构筑单元, 不仅显著增加了反应活性位点, 还赋予材料复杂的电子结构与稳定的几何构型, 展现出更优的电催化性能和调控潜力. 尽管相关研究日益增多, 但系统性总结仍较缺乏, 尤其在催化机制与结构调控策略方面尚缺少深入探讨.

本文围绕多核MOFs在电催化领域中的研究进展进行系统综述, 内容涵盖合成策略、表征方法、催化机制、性能调控及电催化应用五个方面. 首先, 归纳了原位组装与预组装两类构建方式, 并分析了合成过程中金属团簇结构调控的关键影响因素, 包括反应条件、配体类型及辅助试剂等. 其次, 介绍了多种原位表征技术(如红外光谱、拉曼光谱、X射线吸收精细结构、X射线光电子能谱等)在多核MOFs研究中的应用, 探讨它们对金属中心价态变化、配位环境演化和中间体形成过程的实时监测作用, 并分析其优缺点. 系统总结了多核MOFs在析氢、析氧、氧还原、CO2还原、氮还原以及硝酸盐还原等典型电催化反应中的应用进展与催化作用机制. 在此基础上, 重点探讨了其在电催化过程中的作用本质. 多核金属团簇结构中金属位点间的协同作用、电子耦合以及构型调节可有效优化反应物的吸附与活化路径, 促进电子传输, 并稳定关键中间体, 从而显著提升催化性能与反应选择性. 此外, 重点讨论了多核MOFs的性能调控策略. 通过调节金属簇的核数、组成、电子结构及引入缺陷位点, 可实现对催化活性和选择性的精准调控; 同时, 通过配体功能化及活性位点微环境的调控, 也能进一步优化催化过程中的动力学行为与电子输运效率. 这些调控手段在不同反应体系中均展现出显著的性能提升效果. 最后, 指出当前多核MOFs在规模化制备、结构稳定性和真实活性位点识别方面仍面临挑战. 未来研究应加强构效关系的深入解析, 发展高通量筛选与多模态原位表征技术, 并推动多核MOFs材料向器件集成与工程化方向转化.

综上, 本文综述了多核MOFs的可控合成、原位表征、反应机制、调制策略和电催化应用, 并着重讨论了吸附、活性位点和电子转移在电催化过程中的作用. 该论文为多核MOFs的设计与应用提供了系统参考, 推动其在清洁能源催化体系中的应用进程.

Abstract:

Metal-organic frameworks (MOFs) with mononuclear metal ion nodes have garnered significant attention in the electrocatalytic field owing to their high surface area and tunable structures, but their development is critically hindered by the limitation of active site availability. In contrast, multinuclear MOFs exhibit notable advantages by offering multi-metal active sites, constructing complex structures, enhancing structural and thermal stability, and coupling with in-depth studies on catalytic mechanisms, endowing them great application potential in complex multi-electron reactions. This work provides a comprehensive review on the precise construction, in-situ characterizations, reaction mechanisms, modulation strategies, and electrocatalytic applications of multinuclear MOFs, underlying their role in electrocatalytic processes with a focus on adsorption, active sites, and electron transfer. The effects of spin, polarization, orbital coupling, and pore confinement on catalytic performance are systematically elucidated. Furthermore, the unique tuning strategies of multinuclear MOFs are summarized to guide the precise construction, including adjusting the type and number of metal cores, optimizing electronic structures, and manipulating defects. Lastly, the future trends in the development of multinuclear MOFs for electrocatalysis are envisioned, laying a solid foundation for their practical applications.
