The oxide composites based on titanium dioxide modified by molybdenum have been synthesized. The peculiarities of the formation of these composites their physico-chemical and photocatalytic properties have been studied. It is shown that the modification of TiO2 with molybdenum provides obtaining nanodispersed powders (from 8.3 to 12.1 nm) with a free specific surface from 279 to 190 m2/g, respectively. It is shown that the synthesized composites have significantly higher photocatalytic activity (PCA) relative to unmodified TiO2 of similar genesis and industrial titanium dioxide P-25 of Degussa by the example of decomposition of various dyes.
