Synthesis of iron oxide nanoparticles at low bath temperature: Characterization and energy storage studies

Ferric oxide powders were cathodically electrodeposited at a fixed bath temperature 8 °C. The obtained powders were characterized by X-ray diffraction (XRD), scanning electron microscopy(SEM), transmission electron microscopy (TEM), Fourier transform infrared (FTIR) spectroscopy, differential scanning calorimetry (DSC) and thermogramimetric analysis (TGA). Scanning electron microscopic examination of the resultant powders revealed the formation of iron oxide nanoparticles with a grain size of approximately 20 nm. The adhesive deposit is obtained by reducing bath temperature. The increased adhesion is believed to result from the reducing kinetics energy of molecules and the rate of gas bubbling the electrode surface.
