A combined electrochemical/chemicalmethodwas developed in order to synthesize manganese ferrite nanoparticles. The synthesis was carried out in an electrochemical cell containing iron as anode and cathode electrodes and an electrolyte solution of manganese chloride and tetrabutyl ammonium bromide. A usual XRD, STEM compositional mapping images and ICP analysis showed the formation of spinel structure and the presence of Mn, Fe and O in the nanoparticles (NPs) with a stoichiometry Mn0.5Fe2.5O4. The nanoparticle size, shape, and morphology were characterized using electron microscopy and X-Ray absorption spectroscopy, and SQUID measurements were carried out to determine the magnetic behavior. This sample was compared with a same composition manganese ferrite obtained by electrochemical synthesis. (C) 2016 Elsevier Ltd. All rights reserved.
