Albumen Assisted Green Synthesis of NiFe2O4 Nanoparticles and Their Physico-Chemical Properties

Abstract

Spinel ferrites with general formula AB2O4 possess fascinating magnetic and electrical properties due to their thermal and chemical firmness. Nickel ferrite (NiFe2O4) is one of the most vital spinel ferrite having inverse spinel structure showing ferrimagnetism that originates from magnetic moment of anti-parallel spins linking the metal ions (Ni2+ and Fe3+). Here a simple technique of self-combustion with aid of albumen is made to synthesize nano crystalline Nickel ferrite (NiFe2O4) particles. The egg white (albumen) used in the synthesis process plays the role of fuel in the combustion process. The powder X-ray diffraction (PXRD) and Fourier Transform Infrared Spectroscopy (FTIR) results indicated that the synthesized nanoparticles are of single phase and show evidence of spinel structure. The Photoluminescence studies showed a doublet peat at 360-380nm. Also the functional groups present in the synthesized nanoparticles was found using FTIR. EDX results give account of the percentage composition of the elements Fe, Ni and O present in the synthesized sample. The Field Emission Scanning Microscope (FESEM) reveals the agglomerated nature of ferrite nanoparticles. Magnetic moment and retentivity of the as synthesized nickel ferrite (NiFe2O4) nanoparticles were obtained using Vibrating Sample Magnetometer (VSM). Dielectric properties of the as prepared samples were measured by two-probe method for various frequencies ranging from 100Hz-1MHz
