Enhancement of electrochemical properties of porous rGO by controlled growth CoFe2O4 nanoparticles

A study area in supercapacitor research is the design and manufacturing of composite electrode materials that combine the advantages of various materials. The rGO/CoFe2O4 composite material is produced by growing cobalt ferrite particles on the surface of rGO using a simple and highly efficient thermal reduction technique. The results show that the electrochemical properties of rGO are significantly improved by the incorporation of cobalt ferrite. rGO sheets are used as supporting frameworks for the CoFe2O4 nanoparticles, while the CoFe2O4 particles provide more active sites for redox reactions. The prepared rGO/CoFe2O4 show excellent electrochemical properties, with a high specific capacitance of 283 F/g at a current density of 0.1 A/g and a specific capacitance retention of 90.5% after 1000 cycles. The attractive performances exhibited by rGO/CoFe2O4 composites make them potential electrode materials for supercapacitors in future.
