Synthesis and Characterization of Magnetite Nanoparticles and the Effect of [Fe(sac)2(H2O)4].2H2O complex on its magnetic properties

Abstract

A novel inorganic complex (shell)@metal oxide (core) was demonstrated by simple and highly efficient synthesis of Fe3O4 nanoparticles (Fe3O4NPs) coated by [Fe(sac)2(H2O)4] .2H2O complex through one-pot reaction of prepared Fe3O4 nanoparticles and [Fe(sac)2(H2O)4].2H2O. The Fe3O4 NPs structure was characterized by infrared spectroscopy (IR), scanning electron microscope (SEM) and energy dispersive X-rays (EDX) while the resulted [Fe(sac)4(H2O)2]@Fe3O4NPs was characterized using IR spectroscopy and XRD. The magnetic feature, which is one of physical properties of Fe3O4NPs and the newly synthesized core-shell [Fe(sac)2(H2O)4]@Fe3O4NPs were examined in order to study how the Fe in its complex effects on the magnetic properties of magnetite nanoparticles.
