Electrochemical synthesis and properties of iron–titanium dioxide composite coatings

Deposition of Fe/TiO 2 composite coatings from a colloidal methanesulfonate electrolyte containing titanium dioxide hydrosol was studied. The TiO 2 content in the composite increases with increasing the dispersed phase content and decreasing the current density. Incorporation of TiO 2 particles into the iron matrix resilts in an increase in the microhardness of the deposit. The electroplated Fe/TiO 2 composite coating was used as a heterogeneous photocatalyst for the decomposition of an organic dye under the action of UV radiation.
