Low-temperature synthesis, structure-sorption characterisics and photocatalytic activity of TiO2 nanostructures

Resumo

The article addresses a practicable and economic low-temperature method of TiO₂ synthesis, which allows us in a specific manner to influence structure-sorption characteristics and photocatalytic activity of samples not at the expense of the change of temperature of finite treatment, but rather by way of varying additions of the precipitant and modifier. This method helped obtain nanodisperse TiO₂ with a developed specific area of the surface and high photocatalytic activity with respect to dyes of the anionic and cationic types. Individually obtained TiO₂ samples display activity even higher than commercial products.
