Redox-couple-assisted CO2 capture on solid-electrolyte reactor

Electrochemical carbon capture offers a promising approach for capturing scarce CO2 from industrial emissions or the atmosphere. Challenges persist in current techniques, such as low capture rates and oxygen sensitivity. This article previews the latest findings by Wang and co-workers published in Nature, reporting the oxygen/ water redox couple in a solid-electrolyte reactor for continuous and modular CO2 capture.
