Abstract

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 CO 2 capture, leading to a CO 2 capture capacity of 3.2 mmol g-super-−1 under simulated flue gas conditions. The sorbent is readily regenerated at 100°C and exhibits good stability over repetitive adsorption‐desorption cycling. © 2011 Society of Chemical Industry and John Wiley & Sons, Ltd
