Effect of Conditions on TiO2 Aerogel Crystallization Using Modified Supercritical Carbon Dioxide.
Cerhová, Marie
This work is focused on a deeper study of TiO2 aerogel SFC with scCO2 modified by mixture of ethanol and water in a ratio 1:1. The effect of temperature (40–100 °C), pressure (10–30 MPa) and modifier concentration in scCO2 (5–15 wt.%) on microstructure, purity and textural properties of TiO2 aerogel was investigated. Processed monoliths were characterized by XRD analysis, Raman spectroscopy and N2 physisorption.
