Abstract

Nanoparticles of copper ferrite (CuFe2O4) were effectively synthesized by sol-gel method. The as-prepared materials were calcined at three different temperatures such as 600 °C, 700 °C and 800 °C for 5 hours and characterized by using Thermo gravimetric analysis/ Differential thermal analysis, X-ray diffraction, Fourier transform infrared spectroscopy, Field emission scanning electron microscopy with Energy dispersive X-ray analysis, Vibrating sample magnetometer and Cyclic voltammetry. Thermal behavior was analyzed by TG/DTA which is confirms that endothermic and exothermic reaction of the as-prepared sample. The XRD study reveals that the structures of single-phase with cubic nano-sized CuFe2O4 were estimated by crystallite size, lattice parameters. FT-IR spectra confirm present two metal oxygen vibrations such as tetrahedral sites and octahedral sites. The surface morphology study was confirmed by FE-SEM, the image clearly showed in spherical structure. EDAX spectrum reveals that the presence of elements such as Cu, Fe and O no other addition peak presented in the sample. The VSM study confirms the M-H loops of copper ferrite nanoparticles and formation of ferromagnetic nature. CV study which confirms that the pseudocapacitive nature of the prepared samples and measured higher specific capacitance values 421Fg-1 at low scan rate was estimated.
