摘要: 电催化二氧化碳(CO2)还原是实现“双碳”目标与碳资源循环利用的核心技术路径，可将温室气体转化为乙烯、乙醇等高附加值多碳(C2+)产物，兼具环境与经济价值。铜基催化剂因独特电子结构可高效催化C-C耦合反应，是唯一能定向生成C2+产物的金属催化体系，但纯铜催化剂存在选择性欠佳、稳定性不足的瓶颈。构建铜基复合材料为解决上述问题提供了有效方案：通过引入杂原子掺杂、金属氧化物等复合组分，形成Cu0/Cu+/Cu2+多价态界面，可协同优化中间体吸附行为、降低C-C偶联能垒，显著提升催化性能。本文系统综述铜基复合材料的主流构建策略(高温热解、刻蚀、溶剂热、电化学法)及其在电催化CO2还原中的应用优势，重点剖析其稳定Cu+活性位点、串联催化富集*CO中间体的核心机制，为设计开发高效、稳定的铜基复合催化剂提供理论参考与技术启示。
Abstract: Electrocatalytic carbon dioxide (CO2) reduction is a core technical pathway to achieve the “dual carbon” goals and carbon resource recycling, which can convert greenhouse gases into high-value-added multicarbon (C2+) products such as ethylene and ethanol, possessing both environmental and economic values. Copper-based catalysts, due to their unique electronic structure, can efficiently catalyze C-C coupling reactions and are the only metal catalytic system capable of selectively producing C2+ products. However, pure copper catalysts suffer from drawbacks of poor selectivity and insufficient stability. The construction of copper-based composites provides an effective solution to these issues: by introducing composite components such as heteroatom doping and metal oxides, and forming Cu0/Cu+/Cu2+ multivalent interfaces, it can synergistically optimize the adsorption behavior of intermediates, reduce the energy barrier of C-C coupling, and significantly enhance catalytic performance. This paper systematically summarizes the mainstream construction strategies (high-temperature pyrolysis, etching, solvothermal method, electrochemical method) of copper-based composites and their application advantages in electrocatalytic CO2 reduction, focusing on analyzing the core mechanisms of stabilizing Cu+ active sites and tandem catalysis for enriching *CO intermediates, so as to provide theoretical references and technical insights for the design and development of efficient and stable copper-based composite catalysts.
