Abstract：
The electrochemical conversion of carbon dioxide (CO2) to valuable chemicals is gaining significant attention as a pragmatic solution for achieving carbon neutrality and storing renewable energy in a usable form. Recent research increasingly focuses on designing electrocatalysts that specifically convert CO2 into ethanol, a desirable product due to its high-energy density, ease of storage, and portability. However, achieving high-efficiency ethanol production remains a challenge compared to ethylene (a competing product with a similar electron configuration). Existing electrocatalytic systems often suffer from limitations such as low energy efficiency, poor stability, and inadequate selectivity toward ethanol. Inspired by recent progress in the field, this review explores fundamental principles and material advancements in CO2 electroreduction, emphasizing strategies for ethanol production over ethylene. We discuss electrocatalyst design, reaction mechanisms, challenges, and future research directions. These advancements aim to bridge the gap between current research and industrialized applications of this technology.
摘要：
作为实现碳中和和以可用形式存储可再生能源的实用解决方案,二氧化碳(CO2)到有价值的化学品的电化学转化正受到极大关注。最近的研究越来越集中在设计专门将CO2转化为乙醇的电催化剂上，由于其高能量密度而成为理想的产品，易于存储，和便携性。然而,与乙烯(具有相似电子构型的竞争产物)相比,实现高效乙醇生产仍然是一个挑战。现有的电催化系统经常受到诸如低能量效率、稳定性差,对乙醇的选择性不足。受到该领域最新进展的启发，这篇综述探讨了CO2电还原的基本原理和材料进展，强调乙醇生产超过乙烯的策略。我们讨论电催化剂设计，反应机制,挑战,以及未来的研究方向。这些进步旨在弥合当前研究与该技术的工业化应用之间的差距。
