Synthesis, Characterization and Catalytic Performance of Nanoferrites Subjected to the Esterification Reaction

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 nanofer… Show more

“…A síntese por reação de combustão destaca-se, principalmente, por ser uma técnica fácil, segura e rápida para produção de pós cerâmicos, requerer menos energia que os métodos de síntese convencionais e tempo de processamento reduzido para poucos minutos. Associado a tudo isto, a literatura reporta a produção de nanoferritas em escala variada desde 2 até 200 g/batelada de reação para diferentes aplicações [10][11][12]. Com base neste contexto, este trabalho teve como objetivo sintetizar ferritas Mn 0,65 Zn 0,35 Fe 2 O 4 por reação de combustão e avaliar o efeito da diluição dos reagentes em água destilada sobre as características microestruturais e magnéticas.…”
