Abstract

The electrochemical CO₂ reduction reaction (CO₂RR) to valuable C₂₊ products emerges as a promising strategy for converting intermittent renewable energy into high-energy-density fuels and feedstock. Leveraging its substantial commercial potential and compatibility with existing energy infrastructure, the electrochemical conversion of CO₂ into multicarbon hydrocarbons and oxygenates (C₂₊) holds great industrial promise. However, the process is hampered by complex multielectron-proton transfer reactions and difficulties in reactant activation, posing significant thermodynamic and kinetic barriers to the commercialization of C₂₊ production. Addressing these barriers necessitates a comprehensive approach encompassing multiple facets, including the effective control of C─C coupling in industrial electrolyzers using efficient catalysts in optimized local environments. This review delves into the advancements and outstanding challenges spanning from the microcosmic to macroscopic scales, including the design of nanocatalysts, optimization of the microenvironment, and the development of macroscopic electrolyzers. By elucidating the influence of the local electrolyte environment, and exploring the design of potential industrial flow cells, guidelines are provided for future research aimed at promoting C─C coupling, thereby bridging microscopic insights and macroscopic applications in the field of CO₂ electroreduction.

C─C耦合在CO2电化学还原制有价C2+产物中的促进作用：从微观基础到宏观应用

电化学CO2还原反应（CO2RR）产生有价值的C2+产品是将间歇性可再生能源转化为高能量密度燃料和原料的一种有前途的策略。利用其巨大的商业潜力和与现有能源基础设施的兼容性，将二氧化碳电化学转化为多碳碳氢化合物和氧合物（C2+）具有巨大的工业前景。然而，这一过程受到复杂的多电子-质子转移反应和反应物活化困难的阻碍，对C2+生产的商业化构成了重大的热力学和动力学障碍。解决这些障碍需要一种涵盖多个方面的综合方法，包括在优化的局部环境中使用高效催化剂有效控制工业电解槽中的C─C耦合。本文从微观到宏观，包括纳米催化剂的设计、微环境的优化和宏观电解槽的开发等方面深入探讨了纳米催化剂的研究进展和面临的突出挑战。通过阐明局部电解质环境的影响，并探索潜在的工业流动电池的设计，为未来的研究提供指导，旨在促进C─C耦合，从而在CO2电还原领域的微观认识和宏观应用之间建立桥梁。
