Nanoscale titanium dioxide synthesized by sol-gel method
Abstract
Nanoscale titanium dioxide of four modifications - amorphous, anatase, brookite and rutile have been synthesized by sol-gel method from Ti (i-OC3H7)4 and TiCl4 precursors. Structural, morphological and dispersion properties of the TiO2 nanoparticles with different modifications have been studied as well as the effect of the pH of the medium, the synthesis temperature, the chemical nature of the precursor and the molar ratio of reactants on the formation of a titania phase with nanoscale particles have been established.
