摘要

CO₂电化学还原技术(ECO₂RR)是一项在常温常压、绿色条件下将CO₂直接转化、增值的重要技术。而阴离子交换膜作为CO₂电化学还原器件中的核心部件,其性能决定着整个膜电极的能量转换效率。理想的阴离子交换膜(AEM)应拥有高的离子传导率、机械性能与化学稳定性,并且能够有效地阻止产物和反应物的交叉渗透,减少ECO₂RR系统的能量损失。但阴离子交换膜在ECO₂RR中的应用还存在着诸多的障碍需要克服。总结了面向ECO₂RR应用的阴离子交换膜的设计、制备与性能,讨论了阴离子交换膜的各项性能对ECO₂RR性能的影响,并展望未来面向ECO₂RR应用的阴离子交换膜的研究方向。

Abstract

Electrochemical CO₂ reduction technology (ECO₂RR) is a crucial method for directly converting and increasing the value of carbon dioxide at ambient temperature and pressure in an eco-friendly way.Anion exchange membrane (AEM),as a key component in ECO₂RR device,plays a vital role in determining its overall energy conversion efficiency.The ideal AEM should exhibit high ion conductivity,mechanical properties and chemical stability.It is also required to effectively prevent the crossover permeation of products and reactants,thereby reducing energy losses in ECO₂RR system.However,the utilization of AEMs in ECO₂RR devices still encounters various challenges that must be addressed.In this context,the design,preparation and properties of AEMs utilized in ECO₂RR were outlined.Furthermore,the influence of properties of these AEMs on the ECO₂RR performance was discussed,and the future research directions of AEM for ECO₂RR applications were envisioned.
