Abstract

High-performance CO₂ sorbents typically contain both alkaline compounds and inert supporting materials. The convention is broken by TiO(OH)₂. The CO₂ sorption capacity of nanostructured TiO(OH)₂ reaches 6.1 mmol g^-1, while its CO₂ sorption selectivity for CO₂/N₂ mixtures is much higher than that of state-of-the-art sorbents, activated carbon and zeolite, which is another surprise.
