Enhanced Photocatalytic Degradation of Direct Blue-1 Dye by Zno Nanoparticles Using Visible Light
Keywords:
ZnO NPs, Direct Blue-1 Dye, Photo-Catalytic Degradation, Visible LightAbstract
Photocatalytic degradation of Direct Blue-1 has been studied in ZnO nanoparticles dispersion medium under visible light. The absorbance of Direct Blue-1 dye under investigation has been found to be decreased in the presence of visible light and ZnO nanoparticles. The degradation studies have been carried out under various parameters such as catalyst loading, initial dye concentration, pH, effect of oxidant and effect of light intensity etc. The photocatalyst ZnO nanoparticles have been found to be more efficient for the degradation of Direct Blue-1 dye than other reported catalysts.
