Effects of Photocatalytic Activity of Iron Doped on TiO₂ Films Using Microarc Oxidation

Abstract:

Titanium oxide films were formed on the titanium surface by micro-arc oxidation (MAO) in Na₃PO₄ solution. Then the titanium oxide films were soaked by Fe (NO₃)₃ aqueous and calcined to improve the activity. The photocatalytic ability of titanium oxide films before and after surface treatment was evaluated by Rhodamine B aqueous solution. The results show that the photocatalytic degradation rate of titanium oxide films is low. After the surface treatment, the iron ion was doped on the titanium oxide films. It was found that the photocatalytic activity of the titanium oxide coatings was enhanced after Iron doped. The photocatalytic decoloration rate was increased from 15.1 % to 42 %.
