Impact of supercritical drying and heat treatment on physical properties of titania/silica aerogel monolithic and its applications

TiO 2–SiO 2 monolithic aerogels were homogeneously prepared using sol–gel method. Critical point of drying time of TiO 2–SiO 2 gels with ethanol was studied at 30–120 min. Subsequently, the gels were dried with supercritical ethanol, resulting in amorphous aerogels that crystallized following heat t...
