Abstract

Titania nanoparticles have been produced by the controlled hydrolysis of tetraisopropyltitanate (TPT) in sodium bis(2-ethylhexyl)sulfosuccinate (AOT) reverse micelles. Particle formation and aggregation were investigated by static and dynamic light scattering and the chemical species by vibrational spectroscopy.

The kinetics of particle formation and aggregation were controlled by varying [H2O]/[AOT] (w 0), [H2O]/[Ti(IV)] and [AOT]/[Ti(IV)]. Nanoparticles, with diameters<10 nm, could be produced at relatively high Ti(IV) concentrations (up to 0.05 M). These nanoparticles aggregated into sols, with colloid sizes of 20 to 200 nm, eventually forming gelatinous precipitates.

Different titania phases were produced, depending on the size of the micellar water pool; small pools (w 0<6) yielded amorphous particles, while larger pools (w 0>10) produced anatase.
