摘要
Background: Nano perovskite-type structures as denoted by ABO(3) (A = RE) have been popular targets of fundamental investigations since they exhibit a wide variety of physical properties depending upon the chemical composition, defects and small changes in atomic arrangements. Methods: GdAlO3: Co2+ (1, 3 &9 mol %) was synthesized using the solution combustion method by using stoichiometric quantities of gadolinium nitrate [Gd (NO3)(3)], aluminium nitrate (Al (NO3)(2), and cobalt nitrate Co(NO3)(2). Results: The morphology, structure and particle size of the prepared GdAlO3: Co2+ sample were characterized by transmission electron microscope (TEM) image. The Fourier transform infrared (FT-IR) spectral analysis confirmed that the as-prepared powder was in pure state. Electrochemical impedance measurements (EIS) of different GdAlO3: Co2+ samples were measured vs. Ag/AgCl in the frequency range of 1 Hz to 1 MHz with AC amplitude of 5 mV at steady-state which clearly indicated that Co2+ dopant is a successful doping material for the fabrication of supercapacitors. Conclusion: Electrochemical impedance measurements (EIS) of different GdAlO3: Co2+ samples were measured vs. Ag/AgCl in the frequency range of 1 Hz to 1 MHz with AC amplitude of 5 mV at steady-state which clearly indicated that Co2+ dopant is a successful doping material for the fabrication of supercapacitors. From a future perspective, we believe that GdAlO3: Co2+ composite material could be a promising electrode material for the fabrication of various sensors, supercapacitors and solar cells.
