Summary: The present work deals with evaluation of the catalytic properties of polyvanadate xerogels deposited on titanium dioxide (anatase). Xerogels of polyvanadates in the form of nanofibers were obtained by sol-gel method. The average sizes of polyvanadate nanoparticles in aqueous solution determined by DLS were equal to 7 and 50 nm. TEM results reveal the formation of nanostructured thin layers of polyvanadates on the surface of TiO 2 particles. The catalytic properties of polyvanadates deposited on the surface of anatase by impregnation method were studied with respect to decomposition of hydrogen peroxide and oxidation of o-xylene under mild conditions.
