Description:
Fe-C-TiO"2 photocatalysts which contained the residue carbon (0.2-3.3mass%) were prepared from a mixture of TiO"2 and FeC"2O"4 through the heating at 673-1173K in Ar. These photocatalysts did not show a high adsorption of phenol, but they were active in photo-Fenton reactions during decomposition of phenol under UV irradiation with addition of H"2O"2. It was proved that Fe^2^+ governed the photoactivity of Fe-C-TiO"2 photocatalysts, it decreased with heat-treatment temperature above 773K. For comparison, Fe-TiO"2 photocatalyst was prepared by heating TiO"2 and FeC"2O"4 at 823K in air for 3h. Phenol decomposition was going much slower on Fe-TiO"2 photocatalyst in comparison with Fe-C-TiO"2, of which mechanism was different, on the former phenol was decomposed by the radical reaction, on the latter through a complex reaction with iron and intermediates of phenol decomposition. Therefore carbon-coating TiO"2 was found to be advantageous for mounting iron and its application for the phenol decomposition via photo-Fenton process.
