Structure and Photocatalytic Properties of TiO2/MoO3 and TiO2/V2O5 Nanocomposites Obtained by Mechanochemical Activation

Аннотация

The TiO₂/MoO₃ and TiO₂/V₂O₅ thin-film nanoheterogeneous photocatalysts obtained by mechanochemical activation of oxides were studied by using the test reactions of probing dye photooxidation, EPR spectroscopy, X-ray diffraction, and atomic force microscopy. It was shown that mechanochemical synthesis yields nanoheterostructures of the oxide–oxide type, in which optimum conditions were created for photogeneration of charge carriers and their accumulation and thus opens up an opportunity of obtaining photocatalytic systems with prolonged oxidative activity.
