A facile green synthesis of nickel ferrite nanoparticles using Tamarindus Indica seeds for magnetic and photocatalytic studies

Magnetic NiFe2O4 nanoparticle (NFNPs) were synthesized by the microwave-assisted method using Tamarindus indica seeds as a green reducing agent’ for better readability. The identification of NFNPs was carried out X-ray powder diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), scanning electron microscope (SEM) with energy dispersive analysis (EDX), transmission microscopy (TEM), UV–Visible and luminescence techniques. Spinel structure single phase has been confirmed XRD an average crystallite size 21 nm. FTIR confirms presence tetrahedral octahedral sites prepared NFNPs. SEM EDAX TEM gives information agglomeration magnetic nanoparticles elemental composition present in narrow distribution particle 28 are visible active band gap 1.92 eV. show effective photocatalytic activity under light irradiation towards degradation anionic Alizarin red S dye cationic Methylene Blue dye. good property VSM studies. can be useful wastewater treatment.
