MOF-derived multi-metal nanomaterials are attracting numerous attentions in widespread applications such as catalysis, sensors, energy storage and conversion, and environmental remediation. Compared to the monometallic counterparts, the presence of foreign metal is expected to bring new physicochemical properties, thus exhibiting synergistic effect for enhanced performance. MOFs have been proved as a good platform for the fabrication of polymetallic nanomaterials with requisite features. Herein, various design strategies related to constructing multi-metallic nanomaterials from MOFs are summarized for the first time, involving metal nodal substitution, seed epitaxial growth, ion-exchange strategy, guest species encapsulation, solution impregnation and combination with extraneous substrate. Afterwards, the recent advances of multi-metallic nanomaterials for electrocatalytic applications, including oxygen reduction reaction (ORR), oxygen evolution reaction (OER) and hydrogen evolution reaction (HER), are systematically discussed. Finally, a personal outlook on the future trends and challenges are also presented with hope to enlighten deeper understanding and new thoughts for the development of multi-metal nanomaterials from MOFs.
金属有机骨架（MOF）衍生的多金属纳米材料在催化、传感器、储能与转化、环境修复等广泛领域的应用中引起了人们的极大关注。与单金属对应物相比，外来金属的存在有望带来新的物理化学性质，从而表现出协同效应，以提高性能。MOFs 已被证明是制备具有所需特性的多金属纳米材料的良好平台。本文首次总结了从 MOFs 构建多金属纳米材料的各种设计策略，包括金属节点取代、晶种外延生长、离子交换策略、客体物种封装、溶液浸渍以及与外加基底的结合。随后，系统地讨论了多金属纳米材料在电催化应用中的最新进展，包括氧还原反应（ORR）、析氧反应（OER）和析氢反应（HER）。最后，对未来的趋势和挑战提出了个人展望，希望为 MOF 衍生的多金属纳米材料的发展提供更深入的理解和新的思路。
