Titanium dioxide photosensitization to visible light can be observed in the presence of chromate(VI) ions adsorbed at the surface of . The resulting materials do not show, however, sufficient stability and photostability-chromium(VI) species desorb from the surface and can be reduced to chromium(III). The stability of such systems has been improved by  impregnation with fluorochromate(VI), , instead of , yielding yellow F-F- material. Fluorides playing the role of anchors enable stronger adsorption of chromates at titanium dioxide. Also composites of water insoluble chromates(VI) with  release significantly lower amounts of  ions. Such materials have been synthesized according to two main strategies-the first one involves precipitation of water insoluble chromates in the presence of  particles () while the second strategy comprises of  synthesis in the presence of insoluble chromate particles (). Visible light induced photocatalytic activity of synthesized materials was studied in the process of 4-chlorophenol (4-CP) oxidation. A considerable photocatalytic activity was observed in the case of  and  type materials (). Among the composites the highest photoreactivity was shown by  (1.7% , mol/mol, calcined at and  (5% , mol/mol, calcined at ).
