Abstract

TiO₂ has gained great popularity for environmental treatment and purification process; however it shows poor absorption of visible light and requires UV light for activation. CNS codoped TiO₂ (CNS-TiO₂) photocatalyst prepared by sol-gel method is visible light active. The photocatalyst was characterized by
x-ray diffraction, scanning electron microscopy with EDAX analysis. Amidoblack-10B dye (AB-10B) solution under visible light irradiation was used to determine the photocatalytic activity. The photocatalytic test indicated that the modified TiO₂ photocatalyst has higher visible light activity than TiO₂.
