Abstract The characteristics and CO 2 adsorption of mesoporous silicas including MCM-41, SBA-15, and pore-expanded MCM-41 with pore size in a range of 2–17 nm, modified by mono-, di-, and tri-aminosilanes were examined in this study. The adsorption data show that SBA-15 possessing a proper pore size accommodated amines exhibit the best CO 2 adsorption capacity as 2.41 mmol CO 2 /g at 333 K. The corresponded CO 2 adsorption efficiencies, represented by CO 2 /N molar ratios, were as high as of 0… CONTINUE READING
