Devolopment of Co-doped Fe2O3 Nanoparticles for Electrochemical Supercapacitor
Abstract
Co-doped Fe2O3 nanoparticles were synthesized by the co-precipitation method. These crystalline nanostructures were characterized using X-ray powder diffraction (XRD), scanning electron microscopy (SEM), and transmission electron microscope (TEM). The electrochemical characteristics include charge–discharge cycling, which improves the conductivity and capacitance for the high-performance supercapacitor. The CV analysis of the pure Fe2O3 and Co-doped Fe2O3 electrode was distinctive in the 1 M KOH solution case. The nanoparticle size electrode reveals enhanced specific capacitance compared to Co-doped Fe2O3 and Fe2O3 to the electrode has a specific capacitance of about 33.50 F×g-1 and 13.74 F×g-1 with a scan rate 5 mV×s-1.
