Studies on Photocatalytic Degradation of Methylene Blue by Eu³⁺/Gd³⁺ Co-Doped TiO₂

Abstract:

The 0.05%Gd³⁺ /0.4%Eu³⁺ co-doped TiO₂ composite nanopowders have been prepared by sol-gel method and characterized by the techniques such as XRD, SEM/EDAX. The photocatalytic degradation of Methylene blue in aqueous solution was used as a probe reaction to evaluate their photocatalytic activity. The results show that the 0.05%Gd³⁺ /0.4%Eu³⁺ co-doped TiO₂ are only structuresd by anatase phase with grain sizes of about 16nm at 540 °C for 4 h. The photocatalutic degradation of Methylene blue was 96.7% in 120 min of irradiation when the pH value was 9.
