Resum: Cobalt ferrite-graphene nanoplatelets ((CFO)(GNPs)) nanocomposites are promising for efficient photocatalysis and high-performance supercapacitors. Multifunctional (CFO)(GNPs) nanocomposites prepared via facile chemical method have been investigated for their physio-chemical characteristics like crystal structure, morphology, chemical composition, optical properties, infrared vibrational modes, photocatalytic and supercapacitor applications. Interestingly, the photocatalytic activity of CFO nanostructures has been improved significantly from 38. 3% to 98. 7% with the addition of graphene which can be attributed to control over recombination of charge carriers. It is also found that the specific capacitance of the prepared (CFO)(GNPs) nanocomposite electrode at 0. 5 Ag is three times higher than that of only CFO based electrode which could be due to the conducting nature of graphene nanoplatelets (GNPs). The enhanced photocatalytic and improved electrochemical characteristics suggest the effective use of prepared nanocomposites in water purification and supercapacitor nanodevices.
