  • Sol-gel synthesis and characterization of various oxide aerogels and NiO and Pd supported aerogels
    Knez, Željko ; Novak, Zoran
    The preparation of aerogels includes several steps: sol-gel synthesis, drying and thermal treatment. Excellent properties of aerogels, obtained with the sol-gel synthesis, were preserved with ... supercritical drying with CO2. Due to this fact, supercritical drying was carried out at the conditions above the binary critical curve of the solvent CO2, where the solvent and CO2 are completely miscible. All produced aerogels were characterized by means of nitrogen physisorption at 77K, single point BET surface area measurements (adsorption of argon-nitrogen gas mixture), X-ray diffraction and thermal analysis.
