Photocatalytic Degradation of Methylene Blue Solution by Fe-doped TiO_2 under Visible Light

摘要

In this paper, Fe(NO_3)_3·9H_2O and TiO_2 were selected as raw materials. Fe_2O_3/TiO_2 photocatalyst was prepared by the impregnation method. The degradation performance of the photocatalyst for methylene blue solution was studied in detail under the tungsten light source environment. The results showed that Fe_2O_3/TiO_2 had the good photocatalytic properties, and that methylene blue had a higher degradation rate at about 60min. In a certain range of loading, degradation gradually increased with the amount of doped iron. The catalytic performance was high at the basic condition. The degradation rate decreased with the higher initial concentration of methylene blue. The photocatalyst with good performance has been prepared.
