Original Abstract Submitted
Compositions corresponding to amine-functionalized organosilica materials are provided, along with methods of making such materials and methods of using such materials. The amine-functionalized organosilica materials are formed in part by using a single step synthesis process based on condensation of an alkoxy-substituted cyclic organosilane precursor in the presence of an aminosilane precursor so that an amine-functionalized polymer is formed. An acyclic alkoxy silane compound can also be used during the condensation to provide a secondary monomer that facilitates formation of the gel. The amine-functionalized organosilica materials are also formed in part by using at least one of a supercritical drying process and a freeze drying process. By using a supercritical drying process and/or a freeze drying process, an amine-functionalized organosilica material can be formed that has improved properties for sorption of CO.
