The Stabilizing of Anatase Aerogel at High Temperature.

Stable anatase is attractive to its notable functions for photo catalysis and photon-electron transfer. Stable anatase TiO2 containing amorphous SiO2 aerogel was prepared by hydrolysis of Ti (OC3H7)4 and Si (OC3H7)4 in a 2-propanol solution with acid catalyst. The solvent in wet gels was supercritic...
