Continuous decoupled redox electrochemical CO₂ capture.

ABSTRACT: Electrochemical CO₂ capture driven by renewable electricity holds significant potential for efficient decarbonization. However, the widespread adoption of this approach is currently limited by issues such as instability, discontinuity, high energy demand, and challenges in scaling up. In this study, we propose a scalable strategy that addresses these limitations by transforming the conventional single-step electrochemical redox reaction into a stepwise electrochemical-chemical redox process. Specifically, the hydrogen evolution reaction (HER) at the cathode and the oxidation of a redox carrier at the anode are employed to modulate the pH of the electrolyte, thereby facilitating effective CO₂ capture. By decoupling the electrochemical swing for CO₂ capture f
