Preparation, characterization and photocatalytic degradation of congo red by ZnZrO۳/ZnO/ZrO۲

Un-doped and Cd-doped ZnZrO۳/ZnO/ZrO۲ nano composites (CDZZ-NCPs) (CD۰-۴) 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 (CD۰-۴) 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 ۰.۰۳ g of ZnZrO۳/ZnO/ZrO۲ nano composites can degradate ۵۰ mL of CR solution (۱۰ ppm) during ۵ minutes (up to ۹۱.۳%).
