- Abstract
- Mesoporous SBA-15 silica materials were synthesized in short time from one hour ultrasonic irradiation, followed by I - 3 h gelation in acidic media. The particle morphology of these sonochemically synthesized mesoporous materials was nearly spherical. Titanium was directly incorporated into SBA-15 silicate framework through sonochemical co-condensation of Ti(O-iPr)(4) and Si(OEt)(4). The Ti-incorporated SBA-15 silica exhibited good catalytic activity for the oxidation of 2,6-di-tert-butylphenol.
