Tartalmi kivonat:In this paper was studied the adsorption-desorption of CO2 and the effect of temperature on amino-functionalized mesoporous materials by using temperature programmed desorption – TPD method. The adsorption of CO2 and its TPD method was investigated using thermogravimetric analysis coupled with a Pfeiffer-Vacuum-Thermo Star mass spectrometer. For this purpose MCM-41, SBA-15 and SSBA-15 functionalized mesoporous materials were prepared and investigated at different adsorption-desorption temperatures: 50, 60, 70 and 80°C. These composites were also characterized from the structural point of view: FT-IR spectroscopy and nitrogen physisorption at 77K.
