THE PREPARATION AND PHOTOCATALYTIC PERFORMANCE OF FE-DOPED TIO2/GO PHOTOCATALYSTS.

Fe-doped TiO2/GO photocatalysts were synthesized with tetrabutyl titanate, acetylacetone, ferric chloride and graphite powder by hydrothermal method. The photocatalysts were characterized by UV–visible spectroscopy, FTIR and BET. The photocatalytic efficiencies of the catalysts were studied by degradation with rhodamine B(Rh B) as a representative organic under visible light irradiation. The results indicated that ferric acetylacetonate improved the RhB absorption of TiO2 and the graphene accelerate the electron conduction. The synergistic effect of the two improved the photocatalytic performance of TiO2.
