摘要：
Fe doped TiO2 ceramic films were fabricated on carbon steel by plasma electrolytic oxidation. The microstructure of the film was characterised, and the photocatalytic activities of the films were evaluated. The results showed that the phases of the films were anatase TiO2 and Al2TiO5. The film surface was rough and porous. With increasing the treatment time, the pores on film surfaces gradually became deep and large, which made the film surfaces rougher. Fe-TiO2 films showed red shift in photoresponse towards the visible region. The photocatalytic activities of the films were evaluated by photocatalytic oxidation of Rhodamine B aqueous under visible light irradiation. The results revealed that the film showed visible light photocatalytic activity. With increasing treatment time, the degradation rate of rhodamine B gradually increased and the highest degradation rate was similar to 80% in visible light irradiation for 6 h.
