Photocatalytic dye degradation properties of Zinc Copper Ferrites nanoparticles

In the present study, new multi-components spinel ferrite Zinc doped metallic ferrites are investigated. The synthesized compounds consisting of Zinc copper ferrite nanostructures were developed using the Co-precipitation technique. Powder X-ray diffraction pattern (XRD) confirms the formation of the spinel phase for all the samples. The lattice constant was studied through powder X-ray diffraction data analysis. The lattice constant of all Zinc copper ferrite concentration was found to be less than that of bulk values. The chemical composition, surface morphology and crystallinity of the samples have been examined by scanning electron microscopy (SEM) and High-Resolution Transmission Electron Microscope (HRTEM). Besides, selected area electron diffraction (SAED) confirms the evolution of phases and Energy Dispersive X-ray (EDX) respectively. The effect of Zinc copper ferrite nanoparticles, the magnetic properties were investigated by using Vibration Sample Magnetometer (VSM). The obtained hysteresis (M-H) curves of all the samples were analysed under the applied magnetic field of range ± 10 K Oe at room temperature. The magnetic properties such as saturation magnetisation (Ms), remnant magnetization (Mr) and coercivity (Hc) values are calculated. The data obtained from magnetic studies, the variation among the magnetic properties have been investigated for annealed 600 °C sample. The prepared Zinc copper ferrite nanoparticles should be extended to various potential applications, such as photodegradation of methylene blue (MB) dye under visible-light irradiation and results showed that 65% of the dye was degraded.
