| Özet |
| Photocatalysis has gained a great interest for the degradation of organic pollutants in aqueous media. This effective advanced oxidation technique is basically based on the oxidation of the target molecule by hydroxyl radicals. The most widely preferred and powerful photocatalyst is titanium dioxide (TiO2), but it has limited use under solar light because of its band gap energy. This is a major drawback for various possible applications. In order to overcome this disadvantage, doping the photocatalyst with metals and non-metals to narrow the band gap can be applied. In this work, we have prepared visible light active photocatalysts by using wet-impregnation method. Decolorization of two different classes of dyes, Rhodamine B and Congo Red, was carried out under simulated solar light with doped TiO2. The photocatalytic performances of non-metal doped (C, N, Se), metal doped (Cu, Fe) and codoped (N/S) TiO2 photocatalysts were investigated by UV-vis studies and removal percentage calculations. |
