Mesoporous Amine-Bridged Polysilsesquioxane for CO2 Capture

A novel class of amine-supported sorbents based on amine-bridged
mesoporous polysilsesquioxane was developed via a simple one-pot
sol-gel process. The new sorbent allows the incorporation of a large
amount of active groups without sacrificing surface area or pore
volume available for CO2 capture, leading to a high CO2 capture
capacity under simulated flue gas conditions. The sorbent is readily
regenerated at relatively low temperatures and exhibits good stability
over repetitive adsorption-desorption cycling.
