One step synthesis Pd/NiO@rGO/CNTs nanocomposite for energy storage as supercapacitor application

Abstract

Abstract In this study, graphite oxide was reduced into reduced graphene oxide nanosheets (rGO NSs) by microwave with metal acetate of nickel and palladium to form the rGO-carbon nanotubes (CNTs) containing palladium (Pd) and nickel oxide (NiO) nanocomposite (Pd/NiO@rGO/CNTs nanocomposite). The synthesized nanocomposite presents remarkable performance for supercapacitor application especially in stability, exhibiting specific capacitance of 24 F/g at scan rate of 10 mV/s and excellent capacitance retention of 95% after 500 consecutive CV cycles at scan rate of 100 mV/s.
