Abstract: It was shown that modifying titanium dioxide particles with ammonium 6-molybdoferrate (II) and ammonium 6-molybdonickelate (II) gives the photocatalyst the ability to accumulate a photogenerated charge and maintain oxidative activity for some time after ultraviolet irradiation. In this case, heteropolymolybdates not only ensure the accumulation of a photoinduced cathodic charge, but also the conversion of hydrogen peroxide, formed during the oxidation of reduced forms of heteropolymolybdates with air oxygen, to highly active hydroxyl radicals.
Keywords: nanodispersed titanium dioxide, photochemistry, polycondensation of oxoacids of transition metals, ultraviolet radiation, heteropolymolybdates.
