In this current research work, the preparation and properties of nickel ferrite nanoparticles were studied. Using nickel and ferric nitrates and citric acid, NiFe₂O₄ nanoparticles were prepared by a simple and cost-effective sol-gel auto-combustion method. The material used for this purpose was in the form of powder and also reagent grade chemicals were used for this manufacturing. Then the resultant powder was crushed into particles by using mortar and pestle. The phase formation of the NiFe₂O₄ was investigated by XRD and SEM techniques. X-ray diffraction (XRD) measurements were made it possible to approve the structural properties of the prepared samples. The morphology of these samples was explored through scanning electron microscopy (SEM). Thermal properties were studied by the thermal analyzer. The photocatalysts in an aqueous solution were studied under directly visible irradiation of the ferrite sample. After which the photocatalytic activity of the resultant product was observed by UV visible spectrometer.
