Abstract

Ferrites are known for their significant properties in various fields. In this work, Chromium substituted nickel ferrites with general composition NiCrxFe2-xO4 (x= 0, 0.25, 0.5, 0.75, 1) were prepared using sol gel auto combustion method. The structural characterization of the samples was carried out using X-ray diffraction (XRD) which confirmed the presence of single-phasic spinel structure and energy dispersive X-ray (EDX) spectroscopy analysis confirmed the presence of all ions as per the stoichiometric ratios.  Surface morphology of the samples has been investigated using Field Emission Scanning Electron Microscope (FESEM). The bandgap of the prepared samples was measured using UV-Visible-Diffuse Reflectance Spectroscopy (UV-Vis-DRS Spectroscopy). The antibacterial properties of the prepared compounds were tested against gram-positive and gram-negative bacterium and found that antibacterial property decreased with increase in concentration of Chromium for gram-positive bacteria.
