Abstract: In this study, the electrochemical characteristics of manganese ferrite (MnFe 2 O 4) nanoparticles were assessed using various electrochemical techniques, including cyclic voltammetry (CV), galvanostatic charge–discharge analysis, and electrochemical impedance spectroscopy. The electrode material comprising MnFe 2 O 4 nanoparticles with a nanorod spinel structure was synthesized via the sonochemical route and the dimensions in of the nanoparticles ranged from 16 to 24 nm. X-ray diffraction, Fourier transform-infrared spectroscopy, Raman spectroscopy, scanning electron microscopy, energy dispersive X-ray spectroscopy, transmission electron microscopy, and diffuse reflectance spectroscopy were used to determine the characteristics of the MnFe 2 O 4 nanoparticles. HCl and NaOH were used as electrolytes to study the electrochemical behavior of the nanoparticles. The specific capacitance values determined from the CV curves obtained using the MnFe 2 O 4 versus Ag/AgCl electrodes at an AC amplitude of 5 mV and in the frequency range from 1 Hz to 1 MHz in acidic and basic electrolytes with concentrations of 0.1 M were 4.2566 F g−1 and 2.2099 F g−1, respectively. The application of MnFe 2 O 4 as a photocatalyst under ultraviolet light degraded the dyes comprising methylene blue and Drimaren yellow by up to 96% and 7%, respectively. The results obtained in this study verified the potential applications of sonochemically synthesized MnFe 2 O 4 in semiconductors, sensors, and energy storage devices. • MnFe 2 O 4 nanoparticles synthesized using sonochemical method. • Electrochemical properties of MnFe 2 O 4 nanoparticles examined. • MnFe 2 O 4 nanoparticles have possible sensor and supercapacitor applications. • MnFe 2 O 4 acted as photocatalyst to degrade dyes under ultraviolet light.
