Abstract

The urgent need to reduce greenhouse gas emissions, particularly carbon dioxide (CO2), has led to intensive research into novel techniques for synthesizing valuable chemicals that address climate change. One technique that is becoming increasingly important is the electrochemical reduction of CO2 to produce carbon monoxide (CO), an important feedstock for various industrial processes. This comprehensive review examines the latest developments in CO2 electroreduction, focusing on mechanisms, catalysts, reaction pathways, and optimization strategies to enhance CO production efficiency. A particular emphasis is placed on the role of ion exchange membranes, including cation exchange membranes (CEMs), anion exchange membranes (AEMs), and bipolar membranes (BPMs). The review explores their advantages, disadvantages, and the current challenges associated with their implementation in CO2 electroreduction systems. Through careful analysis of the current literature, this report aims to provide a comprehensive understanding of state-of-the-art methods and their potential impact on sustainable CO production, with a special focus on membrane technologies.

电化学CO2还原膜选择的挑战与机遇。
迫切需要减少温室气体排放,特别是二氧化碳(CO2),这导致了对合成有价值化学品的新技术的深入研究,以应对气候变化。一种越来越重要的技术是电化学还原二氧化碳以产生一氧化碳(CO),这是各种工业过程的重要原料。本文综述了二氧化碳电还原的最新进展,重点介绍了提高CO生产效率的机理、催化剂、反应途径和优化策略。特别强调离子交换膜的作用,包括阳离子交换膜(CEMs),阴离子交换膜(AEMs)和双极膜(bpm)。这篇综述探讨了它们的优点、缺点,以及目前在二氧化碳电还原系统中实施它们所面临的挑战。通过对当前文献的仔细分析,本报告旨在全面了解最先进的方法及其对可持续CO生产的潜在影响,特别关注膜技术。
