DUAL FUNCTIONAL AMINOSILICA FOR CO2 CAPTURE
This abstract first appeared for US patent application 18915696 titled 'DUAL FUNCTIONAL AMINOSILICA FOR CO2 CAPTURE
Original Abstract Submitted
Methods are provided for making amine-functionalized organosilica materials that include additional amine functionalities that are grafted to the composition after the initial synthesis. Methods of using such materials are also provided. It has been discovered that additional aminosilyl groups can be grafted onto amine-functionalized organosilica materials under conditions that substantially preserve the original COsorption capacity of the underlying organosilica material prior to grafting. This allows the additional amines in the grafted aminosilyl groups to increase the net capacity of the grafted material, as opposed to primarily replacing the original COsorption capacity with the sorption capacity of the grafted amine functionalities.
