Abstract: To manufacture nanoscale materials with high surface density, achieving average pore size and volume requires energy-intensive and time-consuming operations. We present a straightforward rapid, and quick approach for synthesizing citric acid coated manganese ferrite (MnFe2O4) nanoparticles through chemical co-precipitation with 1 M NaOH as an oxidative solution. The citric acid coated MnFe2O4 nanoparticles were studied by powder X-ray diffraction, Fourier transform infrared spectroscopy, and scanning electron microscopy. The powder X-ray diffraction results confirm the spinel structure of MnFe2O4 based on face centred cubic lattice parameters. The Fourier transform infrared spectroscopy results confirm the vibrational modes of citric acid coated MnFe2O4. The scanning electron microscope results of the as synthesised citric acid coated MnFe2O4 product had a spherical form with an average diameter of 20 nm. The electrochemical properties of MnFe2O4 nanoparticles were studied using cyclic voltammetry, charge-discharge, and electrochemical impedance spectroscopy using 1M NaOH as a electrolyte. Citric-acid coated MnFe2O4 nanoparticles shows pseudo-capacitance behaviour properties and delivers a specific capacitance value of about 381 F g-1 at 1 A g-1 specific current with 15% retention rate at high specific currents. The specific capacitance remained at 92% after 10,000 cycles at a specific current of 2 A g−1 which is clearly showed.
