Adsorption Properties of Aerosilicagels Obtained by Drying in Supercritical Carbon Dioxide Atmosphere

Mesoporous silica gel samples, including those functionalized with amino groups, were prepared using sol-gel synthesis followed by drying in supercritical carbon dioxide. Relationshi ps between the conditions of preparation and modification of the silica sample and their textural and adsorptive properties are established. The obtained porous materials are considered as promising adsorbents for the recovery of carbon dioxide from gas media.

Key words: aerosilica, adsorption of carbon dioxide, amino-functionalization
