摘要

In this work, cobalt chromium iron oxide (CCFO) nanoparticles and rGO-CCFO (GCCFO) nanocomposites were prepared via the sol–gel auto-combustion and hydrothermal-assisted solution methods, respectively. The XRD analysis confirmed the formation of a crystalline phase for both CCFO and GCCFO. The incorporation of rGO in the nanocomposite structure was further justified by the Raman studies. XPS studies were carried out to investigate the surface chemical characteristics and bonding environments. Field-emission scanning electron microscopy and HR-TEM studies demonstrated that the CCFO nanoparticles with particle sizes of less than 20 nm were uniformly dispersed over the graphene layers. The elemental constitution and homogeneity of the samples were also ratified by EDAX and elemental mapping studies. Electrochemical studies like CV, galvanostatic CD, and EIS showed that GCCFO nanocomposite possesses superior supercapacitive properties with a specific capacitance of 122.5 F/g as compared to the pure CCFO nanoparticles, which showed a capacitance value of 22.23 F/g. The observed enhancement can be credited to the synergetic coupling between rGO and CCFO, leading to improvement in charge storage efficiency.
