Abstract

The SiO₂/CaCl₂ hybrid porous materials were obtained by the two-step hydrolysis and condensation of tetraethoxysilane with (a) replacement of ethanol from alcogel by supercritical CO₂ to obtain aerogel morphology and (b) drying alcogel at ambient to obtain xerogel structures. Aerogels and xerogels containing ∼17 and ∼30 wt % of CaCl₂ (dry matter) were prepared and investigated for adsorptivity of water vapor to obtain sorption capacities in excess of 1 kg of water/kg of adsorbate. The adsorbates obtained can be dried and reused. No notable loss in adsorption capacity was observed during 50 cycles.
