The continuous increase of CO2 concentration in the atmosphere has been imposing an imminent threat for global climate change and environmental hazards. In recent years, the electrochemical or photochemical conversion of CO2 into value‐added chemicals or fuels has received significant attention, as it may enable an attractive means to mitigate the atmospheric CO2 concentration and complete the imbalanced carbon‐neutral energy cycle, as well as create renewable energy resources for human use. Among the different electrocatalysts being studied, Cu‐based materials have been demonstrated as the only category of candidates that allows the conversion of CO2 into a variety of reducing products, including carbon monoxide, hydrocarbons, and alcohols. Herein, the reaction pathways for different Cu‐based catalysts for C1 and C2+ products are introduced. Then, different parameters in tuning Cu‐based electrocatalysts are summarized and discussed, including the morphologies, compositions, crystal facets, and oxide derivation. In addition, various types of parameters for CO2 electroreduction are also described, particularly the option of electrolytes such as aqueous, ionic liquids, and organic solutions. Finally, the current challenges are discussed and the potential strategies to facilitate the future development of CO2 electroreduction are summarized.

纳米结构的铜基电催化剂，可减少二氧化碳排放
大气中CO 2浓度的不断增加已经对全球气候变化和环境危害构成了迫在眉睫的威胁。近年来，CO 2电化学或光化学转化为增值化学品或燃料受到了广泛关注，因为它可能成为减轻大气中CO 2浓度并完成碳中和能量平衡失衡的有吸引力的手段。作为创造供人类使用的可再生能源。在正在研究的各种电催化剂中，铜基材料已被证明是唯一可以转化CO 2的候选材料。分解成各种还原产物，包括一氧化碳，碳氢化合物和醇。在此，介绍了用于C 1和C 2+产物的不同Cu基催化剂的反应途径。然后，总结和讨论了调节铜基电催化剂的不同参数，包括形态，组成，晶面和氧化物衍生。另外，还描述了用于CO 2电还原的各种类型的参数，特别是电解质的选择，例如水溶液，离子液体和有机溶液。最后，讨论了当前的挑战，并总结了促进CO 2电还原未来发展的潜在策略。
