| Description
| - Three mesoporous silica materials with different pore sizes (33 A for small pore size MCM-41; 38 A for SBA-12; 71 A for large pore size SBA-15) and pore connectivity (2D for MCM-41 and SBA-15-type materials; 3D for SBA-12 material) were prepared and functionalized with aminopropyl (AP) ligands by post-synthesis treatment. The materials were characterized by small angle X-ray scattering (SAXS), transmission electron microscopy (TEM), thermogravimetric analysis (TGA) and nitrogen adsorption/desorption experiments. The carbon dioxide sorption on modified mesoporous molecular sieves was investigated by using of microbalances at 25 °C, and the influence of pore size and pore architecture on CO2 sorption was discussed. The large pore silica, SBA-15, showed the largest carbon dioxide sorption capacity (1.5 mmol/g), relating to highest amine surface density in this material.

- Byly připraveny tři mesoporézní siliky s rozdílnou velikostí pórů (MCM-41 s 33 A, SBA-12 s 38 A a SBA-15 se 71 A) a různou konektivitou pórů (2D u MCM-41 a SBA-15, 3D u SBA-12); syntetizované materiály byly funkcionalizovány aminopropylovými ligandy. Charakterizace bylo provedena pomocí maloúhlého rozptylu X-paprsků, transmisní elektronové mikroskopie, termoanalýzy a měření adsorpčních a desorpční izoterem dusíku. Sorpce oxidu uhličitého při 25 oC na takto modifikovaných mesoporézních molekulových sítech byla zkoumána pomocí mikrovah. Byl diskutován vliv velikosti a architektury pórů na sorpci oxidu uhličitého. Širokoporézní silika SBA-15 jevila vzhledem k povrchové hustotě aminopropylových skupin nejvyšší sorpční kapacitu (1,5 mmol/g ) pro oxid uhličitý. Trojrozměrná dostupnost aminových center uvnitř pórů siliky SBA-12 způsobovala rychlejší vzrůst adsorpce oxidu uhličitého ve srovnání s molekulovými síty MCM-41 a SBA-15. (cs)
