Abstract

Electrocatalytic reduction reactions, powered by clean energy sources such as solar energy and wind, offer a sustainable method for converting inexpensive feedstocks (e.g., CO₂, N₂/NO_x, organics, and O₂) into high-value-added chemicals or fuels. The design and modification of electrocatalysts have been widely implemented to improve their performance in these reactions. However, bottlenecks are encountered, making it challenging to further improve performance through catalyst development alone. Recently, cations in the electrolyte have emerged as critical factors for tuning both the activity and product selectivity of reduction reactions. This review summarizes recent advances in understanding the role of cation effects in electrocatalytic reduction reactions. First, we introduce the mechanisms underlying cation effects. We then provide a comprehensive overview of their application in electroreduction reactions. Characterization techniques and theoretical calculation methods for studying cation effects are also discussed. Finally, we address remaining challenges and future perspectives in this field. We hope that this review offers fundamental insights and design guidance for utilizing cation effects, thereby advancing their development.

电催化还原反应中的阳离子效应：最新进展

以太阳能和风能等清洁能源为动力的电催化还原反应提供了一种可持续的方法，可将廉价原料（如 CO2、N2/NOx、有机物和 O2）转化为高附加值化学品或燃料。为了提高电催化剂在这些反应中的性能，人们广泛采用了电催化剂的设计和改性方法。然而，由于遇到了瓶颈，仅靠开发催化剂来进一步提高性能具有挑战性。最近，电解质中的阳离子已成为调整还原反应活性和产物选择性的关键因素。本综述总结了在理解阳离子效应在电催化还原反应中的作用方面的最新进展。首先，我们介绍了阳离子效应的基本机制。然后，我们全面概述了阳离子效应在电还原反应中的应用。我们还讨论了研究阳离子效应的表征技术和理论计算方法。最后，我们讨论了这一领域仍然存在的挑战和未来展望。我们希望本综述能为利用阳离子效应提供基本见解和设计指导，从而推动阳离子效应的发展。
