An efficient electrochemical performance of Fe2O3/CNT nanocomposite coated dried Lagenaria siceraria shell electrode for electrochemical capacitor

摘要

alpha-Fe2O3/CNT nanocomposite was successfully synthesised via in-situ co-precipitation method. The structural properties were studied by X-ray diffraction (XRD), Transmission electron microscopy (TEM) and X-ray photoelectron spectroscopy (XPS). The nanocomposite was uniformly coated on dried shell of Lagenaria siceraria (LS) and directly used as the working electrode for electrochemical investigation. It was found that the as prepared Fe2O3/CNT-LS electrode exhibited high capacity, better cycling stability and rate capability. This improved performance was attributed to the spongy, fibrous and networking structure of Lagenaria siceraria dried shell, which allowed fast diffusion of electrolyte ions and structural stability. This Fe2O3/CNT-LS electrode can be promising candidate for energy storage applications.
