Abstract

This work reports the synthesis of NaCr₂O₄/GO nanocomposite using co-precipitation method for energy storage applications. Characterizations e.g., scanning electron microscopy (SEM) and X-ray diffraction (XRD) were performed to investigate the important optical and structural properties. The Crystalline size is seen to decrease from 28 nm for sodium chromite to 16.56 nm for nanocomposite NaCr₂O₄/GO. Raman results showed the existence of characteristic peaks for NaCr₂O₄/GO. Using cyclic voltammetry, the specific capacitance for NaCr₂O₄/GO was measured to be 455.5 F/g. The NaCr₂O₄/GO nanohybrids depicted significantly higher values of specific capacitance combined with extremely low charge transfer resistance, useful for various applications.
