摘要:

近年来, 全球对于清洁能源技术的需求日益增长, 利用太阳能和风能等可再生能源驱动的电化学还原反应成为实现可持续化学生产的重要途径. 将廉价原料(如CO2, N2/NOx, 有机物, O2)升级为高附加值的化学品或燃料, 为能源转换和化学品生产提供了新的可能. 在过去几十年里, 为提高电化学还原反应活性, 研究人员开发和改良了许多种类的电催化剂. 然而, 仅依赖催化剂的优化提高催化性能仍存在局限性. 研究表明, 在电化学还原反应中, 电解质中阳离子的种类和浓度对反应活性和产物选择性有重要影响. 因此, 深入探讨阳离子效应在电催化还原反应中的作用机理及其应用对于推动清洁能源和绿色化学领域的电化学研究具有重要意义.

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/NOx, 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.
