Abstract
A system for direct air capture of CO(DACC) includes a membrane formed from compacted layered material and configured to draw COand HO from air on a feed side of the membrane into interlayers in the membrane through gas over-solubility induced by nanopore confinement and a differential solubility of COover Nand Oin HO. The membrane includes a capture side for collecting a CO-enriched HO flow configured to be generated on the capture side from the COand HO drawn through the membrane. The relative humidity (RH) of the air loads and maintains therein at least one hydration layer of the interlayers of the compacted layered material.
