Electrochemical reduction reactions, as cathodic processes in many energy-related devices, significantly impact the overall efficiency determined mainly by the performance of electrocatalysts. Metal-organic frameworks (MOFs) derived carbon-supported metal materials have become one of star electrocatalysts due to their tunable structure and composition through ligand design and metal screening. However, for different electroreduction reactions, the required active metal species vary in phase component, electronic state, and catalytic center configuration, hence requiring effective customization. From this perspective, this review comprehensively analyzes the structural design principles, metal loading strategies, practical electroreduction performance, and complex catalytic mechanisms, thereby providing insights and guidance for the future rational design of such electroreduction catalysts.
作为许多能源相关装置中的阴极过程，电化学还原反应对主要由电催化剂性能决定的整体效率有重大影响。金属有机框架（MOF）衍生的碳负载金属材料因其可通过配体设计和金属筛选实现结构和组成的可调性，已成为明星电催化剂之一。然而，对于不同的电还原反应，所需的活性金属物种在相组成、电子状态和催化中心构型方面存在差异，因此需要进行有效的定制。从这个角度来看，本综述全面分析了结构设计原则、金属负载策略、实际电还原性能和复杂的催化机制，从而为这类电还原催化剂未来的合理设计提供见解和指导。
