The electrochemical carbon dioxide reduction reaction (ECDRR) driven by clean energy resources (such as wind, solar, etc.) to chemical feedstock and fuels is an attractive route to balance the carbon‐neutral cycle and for regenerating fuels. To date, the ECDRR has been the most promising technology for the conversion of carbon dioxide (CO₂) to carbon‐building blocks, which has a huge market demand and increasing annual global production. Despite tremendous research, the conversion of CO₂ into valuable fuels and chemicals is still challenging due to the highly inert and diverse CO₂ reduction pathways towards high Faradaic efficiency, current density, and stability in the industrialization of ECDRR process. Herein, the most recent developments such as 1) the evaluation of the role of an electrocatalyst according to industrial production demands; 2) the performance of nanostructured electrocatalyst, electrolyte, and devices; 3) advantages and disadvantages of promising metals, such as Au, Ag, and Cu, and single‐atoms, such as Ni, Fe, and Co; and 4) the electrolyte effects, pH effects, and ion effects are described with a vision for ECDRR electrocatalysis towards industrialization. Finally, this review aims to offer forward‐looking, on‐going research/possible activities, together with future perspectives on the ECDRR process from a small‐scale production to industrialization.

走向商业二氧化碳电解

由清洁能源（例如风，太阳能等）驱动的化学二氧化碳还原反应（ECDRR），是化学原料和燃料的一种有吸引力的途径，可以平衡碳中和循环和燃料再生。迄今为止，ECDRR是将二氧化碳（CO ₂）转化为碳构建基块的最有前途的技术，该技术具有巨大的市场需求和全球年产量的增长。尽管进行了大量研究，但由于高度惰性且多样化的CO ₂，将CO ₂转化为有价值的燃料和化学品仍然具有挑战性减少ECDRR工艺工业化过程中实现高法拉第效率，电流密度和稳定性的途径。在此，例如，1）根据工业生产需要对电催化剂的作用进行评价；2）纳米结构电催化剂，电解质和装置的性能；3）有前景的金属（如金，银和铜）以及单原子（如镍，铁和钴）的优缺点；和4）电解质效应，pH效应和离子效应以ECDRR电催化向工业化的愿景描述。最后，本综述旨在提供前瞻性，正在进行的研究/可能的活动，以及从小规模生产到工业化的ECDRR流程的未来观点。
