The oxygen evolution reaction (OER) is a critical electrochemical reaction in water splitting and rechargeable metal–air batteries. It plays a pivotal role in achieving high-efficiency clean-energy production and energy storage in these devices. Transition metal-based bimetallic MOFs (TMB MOFs) with two different metal ions possess specific synergistic effects, which could exhibit OER performance and stability superior to those of the corresponding monometallic MOFs for water oxidation. Benefiting from the diversity of chemical composition and structural type, TMB MOFs can also serve as precursors and templates to obtain alloy-particle-decorated carbon materials with high surface area, or metal compounds such as bimetallic sulfides, phosphides, and hydroxides with atomic-level mixing of heterometallic elements. These materials with high-density active sites exhibit much improved catalytic activity in the water oxidation reaction. This article aims to review the recent progress with TMB MOFs and their derivatives in relation to applications as electrocatalysts in OER, including analysis of the mechanism of the OER process with the assistance of DFT calculations and in situ or operando techniques.

过渡金属基双金属MOF和MOF衍生的催化剂，用于电化学放氧反应

氧气析出反应（OER）在水分解和可充电金属空气电池中是至关重要的电化学反应。在这些设备中实现高效清洁能源生产和能量存储方面，它起着举足轻重的作用。具有两种不同金属离子的过渡金属基双金属MOF（TMB MOF）具有特定的协同效应，与水氧化相比，其OER性能和稳定性优于相应的单金属MOF。得益于化学成分和结构类型的多样性，TMB MOF还可以用作前体和模板，以获得具有高表面积的合金颗粒修饰的碳材料或金属化合物，例如原子级的双金属硫化物，磷化物和氢氧化物杂金属元素的混合。这些具有高密度活性位点的材料在水氧化反应中显示出大大改善的催化活性。本文旨在回顾TMB MOF及其衍生物在OER中作为电催化剂的应用方面的最新进展，包括借助DFT计算和对OER过程机理的分析。原位或操作技术。
