Abstract:

Un-doped and Cd-doped ZnZrO3/ZnO/ZrO2 nano composites (CDZZ-NCPs) (CD0-4) were synthesized by the hydrothermal method. The nano composites were characterized by various techniques such as Fourier Transform Infra-Red spectroscopy (FT-IR), X-ray Diffraction (XRD), Field Emission Scanning Electron Microscopy (FE-SEM) and Energy Dispersive X-Ray Analysis (EDS). The photocatalytic properties of CDZZ-NCPs (CD0-4) were studied by degradation of congo red (CR) dye under sunlight irradiation. The results reveal unique sunlight photocatalytic ability for the degradation of CR. The experimental demonstrated that the 0.03 g of ZnZrO3/ZnO/ZrO2 nano composites can degradate 50 mL of CR solution (10 ppm) during 5 minutes (up to 91.3%).
