Adsorption of Carbon Dioxide on Amine Modified SBA-15 in the Presence of Water Vapor

Novel CO 2 adsorbents were prepared by grafting of various aminosilanes on mesoporous silica SBA-15. CO 2 adsorption capacities of aminosilane modified SBA-15 in the presence of water vapor were comparable to those in theabsence of water vapor. It was found that efficiency of amine increased with increasing surface density of amine.
