10.  Factors that Influence Stability of TiO2 Nanocrystals Size: Taguchi Methods

Authors: O. Giuca and I. Grozescu


Abstract:

This paper presents an experimental study on the stability checking size of titanium dioxide nanocrystals doped with Ag. Because the titanium dioxide is not toxic and can be used as photocatalysts, is used in applications requiring human contact both directly and indirectly. Obtaining method of titanium dioxide, fast hydrothermal method, is at high pressures and temperatures, and is influenced by many factors, including: particle size, concentration or pressure applied to defects in network growth environment. The methodology used to verify the size of nanomaterials offer us control over the size, structure and their properties. The experiments were performed in accordance with the method using a Taguchi L9 experimental plan for each experimental condition was the measured five nanocrystals. The values of model adequacy indicators shows a good correlation between experimental data and those obtained based on mathematical equations of models developed.
