Direct air capture technologies are energy intensive and often utilize pressure and temperature swings for sorbent regeneration. An alternative approach, called moisture-swing direct air capture, relies on the hydrolysis of a confined anion to produce hydroxide anions. These hydroxide anions are active sites for CO₂ capture. Here, the authors examine how confinement affects moisture-swing CO₂ capture and regeneration mechanisms.
