Photocatalysis has found increased attention in recent years due to its potential for resolving of environmental challenges. This work introduces novel and advanced nanomaterial for photocatalytic application. For this aim, nickel ferrite (NiFe2O4) nanoparticles were fabricated via a chemically hydrothermal route. The provided NiFe2O4 nanomaterials were analyzed with scanning electron microscopy (SEM), X-ray diffraction (XRD), energy dispersive X-ray (EDS), Fourier transform infrared spectroscopy (FTIR), and thermogravimetric analysis (TGA). The magnetic properties of prepared nanocomposites were studied via a vibrating-sample magnetometer (VSM). The magnetization amount was determined 23 emu/g via VSM analysis. Also, the SEM analysis confirmed the formation of uniform spherical nanoparticles with a diameter of 71.71 nm. Finally, the as-obtained NiFe2O4 nanoparticles were utilized as photocatalysts for the degradation of methylene blue and methyl orange from wastewater. The results showed that the synthesized nickel ferrite nanoparticles can degrade the 97.4% and 87.9% of methylene blue and methyl orange under UV irradiation. The photocatalytic efficiencies were decreased to 83.5% and 71.1% for methylene blue and methyl orange under visible light respectively.
