Abstract

Spherical submicrometer-sized titanium dioxide (TiO2 or titania) particles were prepared by the sol-gel method from hydrolysis and condensation of titanium alkoxide using different basic catalysts in ethanol/acetonitrile at different annealing temperatures. A systematic study was performed in order to determine the effect on the particle size and shape of the different reagents. Subsequently, they were deposited onto silicon wafers, in order to form a monolayer of TiO2 monodisperse particles. The titania particles were characterized by scanning electron microscopy to determine size and shape, and by X-ray diffraction to find their crystal structure.
