Abstract

Low temperature phase transformation of alkoxide-derived titania was studied under an oxygen flow containing water vapor. The addition of hexylene glycol to the titanium alkoxide solution was effective in transforming rutile phase at low temperature (300°C). Hexylene glycol seems to form a bidentate ligand structure with TEOT in solution state. This bidentate structure promoted the rutile phase at low temperature, under O₂-steam treatment. This modification of TiO₂ gel structure could be monitored by FT-IR and XANES.
