Oxidative Photodegradation of Evans Blue Dye Using N-Doped Zinc Oxide

The photocatalytic degradation of Evans Blue has been studied under visible light in the presence of N-doped ZnO as a photocatalyst. N-doped ZnO was prepared by the solvent free method. The photocatalytic activity of ZnO and N-doped ZnO was compared by investigating the photodegradation of Evans Blue dye under visible light. The effect of different parameters like pH, concentration of the Dye, amount of N-doped ZnO and light intensity on the rate of degradation was also studied. The results revealed that the N-doped zinc oxide photocatalyst shows higher photocatalytic activity compared to pure zinc oxide.
