Влияние кислотно-щелочного состояния исходного раствора на структуру диоксида титана, синтезированного золь-гель методом

Abstract

Titanium dioxide (TiO2) was synthesized by sol-gel method at a different values of pH = 3, 7, 8, 9, or 10. X-ray phase analysis has shown that in an acid rout an anatase phase was crystallized, and in an alkaline rout an amorphous phase of TiO2 was achieved. It was found that the pH variation in an alkaline medium does not affect the atomic structure of TiO2.
