Yellow-GCN (C28H14N2O2S2)textile dye was susessfully degradated by photolysis process undersolar and visible light irradiation using C-N-codoped TiO2thin film photocatalyst.Yellow-GCN [120 mg/L]was irradiated by using 2 visible lamps (philips LED 7 watts 600 lumen and 14 watts 1400 lumen)and solar intensityaround 25.000 luxwith concentration and time variation. Degradation efficiency was measured byspectrophotometer UV-Vis (λ=300-800 nm). The optimum C-N-codoped TiO2thin film used under solar irradiation was 5 coatings. From both diffrent light sources can be concluded that degradation under solar irradiation was better than visible light irradiation due to its degradation percentage during 120 minutes was 30,25%.
