The electrocatalytic carbon dioxide reduction reaction (CO₂RR) is a promising technology that uses renewable energy sources to convert excess atmospheric CO₂ into high-value multi-carbon (C₂₊) products. In the CO₂RR mechanism, adsorbed *CO is recognized as a crucial intermediate, playing a pivotal role in facilitating the formation of C₂₊ products. Currently, Cu-based materials are the most effective catalysts in producing *CO and further coupling it to form C₂₊ products. However, mono-component Cu catalysts still face some challenges, such as low activity, selectivity, and poor stability. Doping engineering has emerged as a valuable strategy for enhancing the performance of Cu-based catalysts in CO₂ electroreduction into C₂₊ products. This comprehensive review presents the recent advancements in CO₂ electroreduction into C₂₊ products over heteroatom-doped Cu-based catalysts, encompassing metallic heteroatoms such as Pd, Au and Ag, as well as non-metallic heteroatoms like P, B and F. The mechanism of enhanced performance through heteroatom doping is specifically highlighted, providing helpful guidance and avenues for the rational design of Cu-based catalysts. Additionally, the review discusses the challenges and prospects associated with the CO₂RR into C₂₊ products, offering a nuanced perspective on this subject.
