| Abstract |
Mesoporous silica materials that have a high specific surface areas and a large pore were prepared by sol-gel method using poly(ethyleneglycol)-block-poly(propyleneglycol)-block-poly(ethyleneglycol)(P123) as a template and tetraethylorthosilicate(TEOS) as a precursor. Amine loaded mesoporous silica were prepared by impregnation methods using tetraethylenepentamine(TEPA) as an amine source. In this study, for confirming to relation between CO2 adsorption property and amine contents, we performed experiments in various amine contents condition on mesoporous silica. The materials were characterized by using FourierTransform-Infrared spectroscopy (FT-IR), N2-sorption, Thermogravimetric analysis (TGA), X-ray Diffraction (XRD), Transmission Electron Microscopy (TEM) and Gas Chromatography (GC) analysis. As an amine contents is increased, CO2 adsorption tends to increase. When the amount of amine was over particular concentration, there was no change in CO2 adsorption.
