Abstract: Improved CO2 sorbents comprised of a mesoporous silica functionalized with a polyamine are obtained by the in-situ polymerization of azetidine. Also included herein are processes utilizing the improved CO2 sorbents wherein CO2 is chemisorbed onto the polyamine portion of the sorbent and the process is thermally reversible.
