Preparation and Characterization of Magnesium Ferrite/ Magnetite Nanocomposite Based Antimicrobial Material

摘要

Nanocrystalline magnesium ferrite/magnetite composite has been prepared by combustion technique. Structural characterization has been performed by X-ray diffraction XRD). Formation of magnesium ferrite/magnetite composite has also been studied by using infrared (IR). The chemical composition and surface morphology of the as prepared material were determined using energy dispersive X-ray (EDX), scanning electron microscope (SEM) and transmission electron microscope (TEM) techniques. SEM and TEM show formation of nano- materials with sponge-like structure. The concentration of constituents, involved in the as synthesized material was determined by using EDX technique. In fact, it was found the concentration of Mg, Fe and O species changes from the uppermost surface layer to the bulk of the system studied. Finally, XRD measurements display formation of MgFe_2O_4/Fe_3O_4 composite. It is well known that iron oxide based nanomaterials have many potential applications in biology due to their significantmagnetic properties.
