TiO(OH)2 can exceed the critical limit of conventional CO2 sorbents: modification needed for high capacity and selectivity

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 gāˆ’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.
