Abstract
Briefly described, embodiments of this disclosure, among others, include carbon dioxide (CO2) sorption structures, methods of making CO2 sorption structures, and methods of using CO2 sorption structures.
Claims17
A CO2 sorption structure, comprising:
- a high surface area structure that includes a plurality of pores in the high surface area structure, wherein each pore has an inside surface, wherein at least the inside surface of the pore includes hydroxyl groups on the surface;
- and
- a hyperbranched polymer covalently bonded to the inside surface of the pore directly to the oxygen of the hydroxyl group on the inside surface of the pore;
- wherein the CO2 sorption structure is an inorganic/organic hybrid structure that is about 10 to 70% organic and about 30 to 90% inorganic.
1 more element
A CO2 sorption structure, comprising:
- a high surface area structure that includes surface hydroxyl groups;
- a hyperbranched polymer covalently bonded directly to at least one surface oxygen of the hydroxyl group;
- wherein the CO2 sorption structure is an inorganic/organic hybrid structure that is about 0.1 to 70% organic and about 30 to 99.9% inorganic.
