Abstract

The CO₂ uptake on nanoscale AlO(OH) hollow spheres (260 mg g⁻¹) as a new material is comparable to that on many metal–organic frameworks although their specific surface area is much lower (530 m² g^¬1versus 1500–6000 m²g^¬1). Suited temperature–pressure cycles allow for reversible storage and separation of CO₂ while the CO₂ uptake is 4.3-times higher as compared to N₂.
