Abstract

The invention relates to regenerative, solid sorbent for adsorbing carbon dioxide from a gas mixture, with the sorbent including a modified polyamine and a nano-structured solid support. The modified polyamine is the reaction product of an amine and an aldehyde. The sorbent provides structural integrity, as well as high selectivity and increased capacity for efficiently capturing carbon dioxide from gas mixtures, including the air. The sorbent is regenerative, and can be used through multiple operations of absorption-desorption cycles.
