Abstract
FT-Raman spectroscopy has been used to study the peptisation of titania hydrolysates produced from tetraiso-propyltitanate (TPT). chemically modified by reaction with a number of carboxylic acids. During peptisation with nitric acid at 333 K, a colloidal sol of well crystallised anatase was formed. Similar sols were formed by heating at 333 K in the absence of HNO3, but at a slower rate. The rate of structural change depended upon the chain length of the modifying acid. Decreases in the anatase band widths occurred during peptisation indicating increased crystallinity upon formation of the colloid. FT-Raman spectroscopy has proven to be an ideal tool for the study of titania colloids.
