Electrochemical carbon dioxide reduction reaction (CO₂RR) offers a promising way of effectively converting CO₂ to value-added chemicals and fuels by utilizing renewable electricity. To date, the electrochemical reduction of CO₂ to single-carbon products, especially carbon monoxide and formate, has been well achieved. However, the efficient conversion of CO₂ to more valuable multicarbon products (e.g., ethylene, ethanol, n-propanol, and n-butanol) is difficult and still under intense investigation. Here, recent progresses in the electrochemical CO₂ reduction to multicarbon products using copper-based catalysts are reviewed. First, the mechanism of CO₂RR is briefly described. Then, representative approaches of catalyst engineering are introduced toward the formation of multicarbon products in CO₂RR, such as composition, morphology, crystal phase, facet, defect, strain, and surface and interface. Subsequently, key aspects of cell engineering for CO₂RR, including electrode, electrolyte, and cell design, are also discussed. Finally, recent advances are summarized and some personal perspectives in this research direction are provided.

铜基催化剂电化学二氧化碳还原制备多碳产品的最新进展

电化学二氧化碳还原反应 (CO ₂ RR) 提供了一种通过利用可再生电力将 CO ₂有效转化为增值化学品和燃料的有前途的方法。迄今为止，CO ₂电化学还原为单碳产物，特别是一氧化碳和甲酸盐，已经很好地实现。然而，将CO ₂有效转化为更有价值的多碳产品（例如，乙烯、乙醇、正丙醇和正丁醇）是困难的并且仍在深入研究中。在此，综述了使用铜基催化剂将CO ₂电化学还原为多碳产品的最新进展。一、CO的作用机理₂ RR 简要描述。然后，介绍了在 CO ₂ RR 中形成多碳产物的催化剂工程的代表性方法，例如组成、形态、晶相、小平面、缺陷、应变以及表面和界面。随后，还讨论了 CO ₂ RR电池工程的关键方面，包括电极、电解质和电池设计。最后，总结了近期的研究进展，并提供了该研究方向的一些个人观点。
