Enhancement of CdO/ZnO/PVC Nanocomposites Behavior on Photo-Catalytic Degradation of Congo-Red Dye under UV Light Irradiation

Abstract:

nanoCdO/ZnO/PVC composite thin films were prepared by simple solution cast method, using tetra hydrofuran as solvent. nanoCdO/ZnO/PVC composite thin films were irradiated by UV light at the range of 365 nm, 312 nm, and 254 nm. The photo-catalytic activity of CdO/ZnO/PVC was examined by photo-catalytic decolourization of congo-red in aqueous solution. nanoCdO/ZnO/PVC composite film exhibited higher photo-catalytic activity under UV light radiation at 365 nm rather than 312 nm & 254 nm. After 90 minutes irradiation by UV light almost 95% congo-red got decolorized. FT-IR studies confirm the complexation behavior of polymer with ZnO and CdO present in the composite.
