Abstract
Tin dioxide-based aerogels were produced by supercritical drying of gels, synthesized using propylene oxide, in CO2 and isopropanol. Aerogels consisted of nanocrystalline cassiterite and had a specific surface area of 210–270 m2/g. Sulfation with sulfuryl chloride imparted superacidic properties to the aerogels (the Hammett acidity function H0 reached values within the range – 11.99 ≥ H0 ≥ –12.7). Superacid SnO2 aerogels demonstrated high catalytic activity in 1-hexene oligomerization and isomerization.
