Abstract
In this paper, Sugimoto model has been employed to study the nucleation and the growth of TiO2 nanoparticles. On the base of this model some parameters of the nucleation and the growth of nanoparticles such as supply rate of the solute (Q0), molar volume of the solid (Vm), and mean volumic growth rate of the stable nuclei during the nucleation period (v) were determined. For this approach, TiO2 nanoparticles were synthesized in two stages in an aqueous solution by using HNO3 and TTIP and TIPO as starting materials. In this experiment, it was obviously observed that the changing of Ti+4concentrations was followed with LaMer diagram. Typical obtained results were v=2.93×102 nm3.s -1 and...
