Utilization of CoFe₂O₄ nanoparticles to harness their electrochemical characteristics

The cobalt ferrite nanoparticles were synthesized using cobalt nitrate and ferric nitrate as precursor materials by combustion method using sucrose as a fuel. The cobalt ferrite nanoparticle materials were analyzed through field emission scanning electron microscope (FESEM) and X-ray diffraction (XRD) spectroscopy. FESEM and XRD techniques reveal that the cobalt ferrite particles are in the crystallite nano range, with their size ranging from 10 to 14 nm. The cobalt ferrite nanoparticle materials have been thermally analyzed by Mettler Toledo and thermogravimetric analysis/differential scanning calorimetry 3+ model; the nanoparticles were found thermally stable at 450°C temperature. Galvanstate 101 (the Netherlands) with three-electrodes system and AUTOLAB potentiostats were used to test electrochemical properties during the synthesis of cobalt ferrite nanoparticle materials; the oxidation and reduction potentials were found to be 384 mV and 186 mV, respectively. Oxidation and reduction currents were found at 35.9 μA and −25.5 μA, respectively. The electrode was made from cobalt ferrite nanoparticles for application, and their properties were excellent.
