Effect of different swelling agents on textural and structural properties of modified mesoporous silica
In this study was carried out the preparation of some large-pore ordered mesoporous silicas using a proper surfactant with different swelling agents. In order to use a micelle swelling agent with a moderate swelling ability we selected three swelling agents: 1-phenyldecane, butyl benzene and mesityl...

In order to use a micelle swelling agent with a moderate swelling ability we selected three swelling agents: 1-phenyldecane, butyl benzene and mesitylene. The aim of these synthesis was to achieve a pore diameter enlargement but in the same time to avoid the formation of heterogeneous and/or poorly defined nanostructure of silica. These composites were characterized by FT-IR spectroscopy, X-ray diffraction at low angles, nitrogen physisorption at 77 K, SEM-EDS. In the view of a possible use of these amino-functionalized mesoporous silicas as adsorbents for CO2 removal, their adsorption– desorption properties towards CO2 were investigated by the TPD method. CO2 adsorption isotherms of amino-functionalized mesoporous silicas measured at 50, 60 and 70 °C showed that the adsorption capacity (mg CO2/g adsorbent) depend on the temperature of adsorption and on the type of swelling agents and amination reagents used. | |
