Abstract

In this work, strontium titanate (SrTiO3), silicon (Si) and eggshell doped SrTiO3 nanoparticles with constant doping concentration and weights were successfully fabricated by a solid-state reaction method. SrTiO3 has applications in semi-conductive ceramics, pyroelectric far-infrared detectors, multilayer capacitors, electro-optical appliances, electromechanical devices, and tuneable microwave capacitors. The prepared samples were examined by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDX), cyclic voltammetry (CV), and electrochemical impedance spectroscopy (EIS). XRD results show that the structure of the SrTiO3 nanoparticles is cubic, and the crystallite size decreased with doping. The fine agglomerated nanosphere morphologies and the elements presented in the sample are explored by SEM and EDX analysis. FTIR band observed at 571 cm-1 is due to Sr-Ti-O stretching vibration. CV analysis reveals the pseudo-capacitive characteristic of prepared samples. EIS confirms that the eggshell-doped SrTiO3 has higher charge transfer resistance compared with pure and silicon-doped SrTiO3 nanoparticles.
