Wastewaters from textile industries contribute to significant volumes of colored and hazardous material pollution. Photocatalytic degradation offers a method reduce organic pollutants, such as dye-containing effluents effectively. Nickel Ferrite (NiFe2O4) receives the most attention in spinel ferrites since it has diverse applications catalysis, sensor technology, spintronics, magnetocaloric refrigeration, high-density data storage devices, etc. We performed green synthesis NiFe2O4 nanoparticles by fruit extract gingerbread tree (Hyphaene thebaica). characterized with Scanning Electron Microscopy (SEM), Transmission (TEM), X-ray diffraction (XRD), Fourier Transform Infrared spectroscopy (FTIR), Raman spectroscopy. The XRD indicates inverse-spinel structure F3dm space group crystallite size measured 30 nm. SEM TEM revealed spheroidal NPs. synthesized tetrahedral octahedral stretching vibrations Ni–O Fe–O, suggested FTIR. Doublet-like peak behavior spectrum indicated presence mixed structure. studied magnetic two different modes, magnetization measurements showed soft ferromagnetic saturation 1.527 emu g−1. For photocatalytic potential, efficiency was 97 % after 90 min at adding 1 g/L nano-catalyst, which shows high catalytic activity NPs under visible light conditions.
