- Abstract
Porous photocatalytic titania film co-doped with Fe and Si was fabricated on carbon steel substrate by plasma electrolytic oxidation (PEO). The microstructure of the film was investigated and the photocatalytic activity of the film was tested by measuring the photodegradation rate of the organic methylene blue (MB). The results revealed that the obtained film was composed of anatase and rutile TiO2 crystalline phases. Fe and Si were co-doped in the film. The film was thick with the thickness of about 25 m. It was double layered with a compact inner layer and loose out layer. The film surface was coarse and porous and was covered with micro pores. The photodegradation rate of MB reached 86% with 3h irradiation of UV, showing a high photocatalytic activity. The method reports a rapid and simple route to fabrication porous crystalline TiO2 film with high photocatalytic activity.
