Global warming and climate change caused by an ever-increasing accumulation of atmospheric CO₂ are reaching alarming levels. In order to address this issue, significant research effort has been dedicated to the development of carbon capture processes for sequestration or utilization of CO₂. Current technologies rely on energy-intensive temperature- or pressure-swing of CO₂ sorbents, limiting the economic feasibility of the process. Herein, we review recent advances in electrochemically mediated CO₂ capture and release. Specifically, redox-active sorbents and mediators provide new opportunities in separation of CO₂ by significantly reducing the energy requirements and widening the scope for system modifications. In particular, strategies for electrochemically mediated regeneration of sorbents in conventional processes, direct capture and release of CO₂ by exploitation of redox-active complexes, and the outlook for electrochemically based carbon capture are covered.

由不断增加的大气 CO ₂积累引起的全球变暖和气候变化正达到惊人的水平。为了解决这个问题，大量的研究工作致力于开发用于封存或利用CO ₂的碳捕获过程。当前的技术依赖于能源密集型的 CO ₂吸附剂的温度或压力摆动，限制了该过程的经济可行性。在此，我们回顾了电化学介导的 CO ₂捕获和释放的最新进展。具体而言，氧化还原活性吸附剂和介质为分离 CO ₂提供了新的机会通过显着降低能源需求并扩大系统改造范围。特别是，涵盖了传统工艺中吸附剂的电化学介导再生、通过利用氧化还原活性复合物直接捕获和释放 CO ₂的策略，以及基于电化学的碳捕获的前景。
