  • Nitrogen-doped TiO2 were prepared by sol-gel method, and charactered by means of XRD, SEM, IR and particles size analysis. Photocatalytic degradation of wastewater from eosin solution was also studied by using nitrogen-doped TiO2 as catalyst and visible light as light source. The influences of the dosage of catalyst, concentration of eosin Y,photocatalytic reaction time and pH were investigated. The optimum conditions are found: the proper dosage of nitrogen-doped TiO2 catalyst is 0.4 g, concentration of eosin Y solution is 20 mg/L, the photocatalytic reaction time is 45 min,pH=4, decolorization rate of eosinY solution is 98.87 %.
