Abstract

The band gap (Eg) of sol-gel derived titania has been determined using UV-Vis spectroscopy. When platinum acetylacetonate was added during titanium tetrabutoxide gelation, a significant diminution of the band gap was observed. Low Eg values were stabilized on heat-treated platinum/titania samples.
