Abstract
- Spinel-type CuFe<subscript>2</subscript>O<subscript>4</subscript> nanoparticles were synthesized by a solvothermal method using ethylene glycol as solvent and polyvinylpyrrolidone (PVP) as dispersant. The characterization results showed that the average diameter of the hollow-spherical CuFe<subscript>2</subscript>O<subscript>4</subscript> was approximately 100 nm with homogeneous morphology and negligible agglomeration. CuFe<subscript>2</subscript>O<subscript>4</subscript> was used as the active electrode material to explore its supercapacitive properties in different concentrations of KOH electrolytes. It was found that the CuFe<subscript>2</subscript>O<subscript>4</subscript> hollow-spherical nanoparticles exhibit potential electronic performance in supercapacitor, with a specific capacitance of 368.2 F/g and capacitance stability retention of 91.0% after 2000 cycles at the current density of 5 A/g in 3 mol/L KOH electrolyte. The present findings demonstrate that the CuFe<subscript>2</subscript>O<subscript>4</subscript> electrode materials can have important implications with practical prospects in energy storage systems.
