Adsorption Properties of Aerosilicagels Prepared by Drying in a Supercritical Carbon Dioxide Medium

Resumo

Mesoporous silicagels, including samples functionalized with amino groups, have been synthesized by the sol–gel method with drying in supercritical carbon dioxide. The textural and adsorption properties of SiO₂ are established to depend on synthesis and modification conditions. The synthesized porous materials are considered promising adsorbents for the recovery of carbon dioxide from gas media.
