Abstract

The paper presents the results of the study of physicochemical and photocatalytic properties of the composites based on tungsten-modified TiO2, calcined at the temperature of 700 °C in the range from 5 to 60 minutes. It was established that short-term calcination for 5 and 10 minutes allows increasing the specific surface area of the powders by 10–30 %. The increase of photocatalytic activity (PCA) of the samples in relation to various organic dyes reaches 16 % in comparison with the samples calcined at 600 °C.
