Amine functionalized KIT-6 for CO2 adsorption at different temperatures
In this paper, pure KIT-6 was synthesized and functionalized with 3-aminopropyl triethoxysilane (APTES) by grafting in aqueous solvent at 80°C. The as-prepared composites were characterized by X-ray diffraction at low angles, FT-IR spectroscopy, TGA-DTA coupled with mass-spectrometry, SEM and N2 phy...

| Tartalmi kivonat: | In this paper, pure KIT-6 was synthesized and functionalized with 3-aminopropyl triethoxysilane (APTES) by grafting in aqueous solvent at 80°C. The as-prepared composites were characterized by X-ray diffraction at low angles, FT-IR spectroscopy, TGA-DTA coupled with mass-spectrometry, SEM and N2 physisorption techniques followed by testing for CO2 adsorption at different temperatures. The CO2 adsorption/desorption performance was investigated by TGA-DTA coupled with mass-spectrometry using TPD method. The results showed that the CO2 adsorption capacity decreases with increasing temperature from 40 to 70 °C. |
