Abstract

This work demonstrates the potential use of triamine-grafted pore-expanded mesoporous silica TRI-PE-MCM-41, for the removal of CO₂ from nitrogen, oxygen and water vapor-containing mixtures. In addition to unprecedentedly high CO₂ uptake at low pressure, high adsorption rate and stability, this material exhibited very high selectivity for CO₂ over N₂ and O₂, regardless of the presence of moisture. It is thus highly suitable for use in CO₂ removal from air, for example in air purification and in closed-circuit breathing systems.
