Synthesis of the TiO2 nanoparticles was carried out by sol-gel method. The optimal conditions for stable TiO2 gel obtaining was determined. The resulting samples were studied by IR spectroscopy. Studies have shown the presence of chemically and physically bounded water in TiO2 powders, dried at 125 ° C. Studying of the influence of the pH on the acid-base properties of the surface of the resulting TiO2 powders was performed by indicator method.
