Abstract: Ni0.5Zn0.5Fe2O4, Mn0.5Zn0.5Fe2O4and Ni0.2Cu0.3Zn0.5Fe2O4nanoferrites were synthesized, characterized and evaluated in terms of their performance as catalysts in the methyl esterification reaction of soybean oil. The nanoferrites were synthesized by combustion and characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) and energy dispersive X-ray spectroscopy (EDX). The XRD patterns show the presence of inverse spinel B(AB)2O4phase. The EDX results confirmed the stoichiometry of the nanoferrite systems, whose morphology consisted of large block-like agglomerates with a brittle aspect and a wide agglomerate size distribution. The results indicate that the Ni0.5Zn0.5Fe2O4nanoferrite was the most active catalyst in the esterification reaction, with conversion rates ranging from 40 to 91%.
