Abstract

The analytical review and the new methods of nano-fi ne titanium dioxide (TiO2) preparation are described. The specifi cs of its photocatalytic activity in the water systems treatment with the removal/decomposition of persistent organic pollutants is discussed. The fi rst of the methods involved is based on the criochemical technology, the second one includes the dissolving of metallic titanium in the alkaline solution under the application of periodic current with the reverse impulse, and the third method is the electrochemical synthesis of TiO2 having the nano-tubular structure.
