The electrocatalytic carbon dioxide reduction reaction (CORR) represents a pivotal technology for mitigating climate change and achieving carbon neutrality, by utilizing renewable energy to transform CO into valuable chemical feedstocks. However, the inherent stability of CO molecules and the competing hydrogen evolution reactions necessitate the development of efficient, cost-effective catalysts. Metal-organic frameworks (MOFs), especially zeolitic imidazolate framework-8 (ZIF-8), are increasingly recognized as attractive materials for catalytic applications, due to their tunable structures, high porosity, and well-defined active sites. Despite such progress, challenges such as poor electrical conductivity and limited selectivity hinder their practical application. This review systematically examines recent advancements in enhancing ZIF-8-based electrocatalysts for the CORR through multidimensional structural engineering strategies. Key approaches include lattice engineering for optimizing morphology and size, modulating the coordination microenvironment chemical doping, constructing heterogeneous interfaces to design composite catalysts, and topological transformation to derive high-performance materials. By correlating structural modifications with catalytic performance, this work elucidates design principles for activity. Additionally, this work also discusses future development directions for ZIF-8-based catalysts according to the current research results, aiming to provide guidance for the rational design of next-generation MOF-based catalysts for sustainable CO conversion and energy storage.
电催化二氧化碳还原反应（CORR）是一项关键技术，通过利用可再生能源将二氧化碳转化为有价值的化学原料，以缓解气候变化并实现碳中和。然而，二氧化碳分子的固有稳定性和竞争性析氢反应使得开发高效、经济的催化剂成为必要。金属有机框架材料（MOFs），特别是沸石咪唑酯骨架结构材料-8（ZIF-8），因其可调节的结构、高孔隙率和明确的活性位点，越来越被认为是催化应用的有吸引力的材料。尽管取得了这些进展，但诸如导电性差和选择性有限等挑战阻碍了它们的实际应用。本文综述系统地研究了通过多维结构工程策略增强基于ZIF-8的CORR电催化剂的最新进展。关键方法包括用于优化形态和尺寸的晶格工程、调节配位微环境的化学掺杂、构建异质界面以设计复合催化剂以及拓扑转变以获得高性能材料。通过将结构修饰与催化性能相关联，这项工作阐明了活性的设计原则。此外，根据当前的研究结果，本文还讨论了基于ZIF-8的催化剂的未来发展方向，旨在为下一代基于MOF的可持续二氧化碳转化和储能催化剂的合理设计提供指导。
