当配备合适的催化剂时，通过电化学CO ₂还原反应(eCO ₂ RR)可以有效地产生一氧化碳、甲烷、乙烯、乙醇、乙烷等增值化学品。其中，乙烯作为石化制造的化学原料尤为重要。然而，尽管其在相对较低的电流密度下可以实现高法拉第效率，但在工业电流密度下乙烯选择性和稳定性的大幅提高提出了巨大的挑战。为了促进eCO ₂ RR用于乙烯生产的工业实施，必须通过了解最新进展、仍然存在的挑战和未来方向来确定关键策略和潜在解决方案。本文从催化剂的形貌、结晶、氧化态、缺陷、组成和表面工程等性能入手，总结和讨论了最新的、创新的eCO ₂ RR制乙烯催化剂设计策略。该综述随后概述了相关重要的最先进技术，这些技术对于推动 eCO ₂ RR 制乙烯进入实际应用至关重要，例如 CO ₂捕获、产物分离和下游反应。最后，提出了集CO ₂捕获、转化、储存和利用于一体的温室模型，为eCO ₂ RR制乙烯提供了理想的前景方向。

Electrocatalytic CO2 Reduction to Ethylene: From Advanced Catalyst Design to Industrial Applications

The value-added chemicals, monoxide, methane, ethylene, ethanol, ethane, and so on, can be efficiently generated through the electrochemical CO₂ reduction reaction (eCO₂RR) when equipped with suitable catalysts. Among them, ethylene is particularly important as a chemical feedstock for petrochemical manufacture. However, despite its high Faradaic efficiency achievable at relatively low current densities, the substantial enhancement of ethylene selectivity and stability at industrial current densities poses a formidable challenge. To facilitate the industrial implementation of eCO₂RR for ethylene production, it is imperative to identify key strategies and potential solutions through comprehending the recent advancements, remaining challenges, and future directions. Herein, the latest and innovative catalyst design strategies of eCO₂RR to ethylene are summarized and discussed, starting with the properties of catalysts such as morphology, crystalline, oxidation state, defect, composition, and surface engineering. The review subsequently outlines the related important state-of-the-art technologies that are essential in driving forward eCO₂RR to ethylene into practical applications, such as CO₂ capture, product separation, and downstream reactions. Finally, a greenhouse model that integrates CO₂ capture, conversion, storage, and utilization is proposed to present an ideal perspective direction of eCO₂RR to ethylene.
