Front Cover: Towards Energy-Efficient Direct Air Capture with Photochemically-Driven CO2 Release and Solvent Regeneration (ChemPlusChem 10/2024)

Abstract

Photochemically driven CO₂ release using metastable-state photoacids (mPAH) initiates with trans–cis photoisomerization, followed by subsequent structural changes and proton transfer to bicarbonate ions resulting from CO₂ capture. mPAHs reversibly regulate solution pH, providing a new avenue towards energy efficient on-demand CO₂ release and solvent regeneration under ambient conditions using abundant solar energy instead of heat. More details can be found in the Concept by Uvinduni I. Premadasa, Ying-Zhong Ma, and co-workers (DOI: 10.1002/cplu.202300713).
