ABSTRACTZnFe2O4 nanoparticles were prepared by hydrothermal reduction approach. A considerable amount of α-Fe2O3 was segregated in the as-synthesized sample, which diffused into the tetrahedral and octahedral sites of the ZnFe2O4 spinel structure with increasing the annealing temperature. The introduction of Fe3+ into the tetrahedral positions was observed by Mössbauer spectra. Magnetization measurements showed an unusual ferrimagnetic behavior of the ZnFe2O4 phase, even at room temperature, confirming the introduction of Fe3+ into the tetrahedral sites of the spinel structure. Catalytic activity measured in the oxidative dehydrogenation of 1-butene reaction increased with increasing annealing temperature, indicating that those interactions of Fe3+ in tetrahedral and octahedral positions also promotes the activity and selectivity to butadiene formation.

Cobalt Zinc Ferrite

Nanoparticles of Cobalt-zinc ferrite (Co0.5Zn0.5Fe2O4) and Cobalt-manganese ferrite (Co0.5Mn0.5Fe2O4) have been synthesized at room temperature by co-precipitation method with and without calcination process. Starting materials for preparation of nanooxides were Co (NO3)2.6H2O, ZnCl2, Fe (NO3)3.9H2O and Mn (NO3)2.4H2O. These salats were mixed in stoichiometric amounts and precipitated with sodium hydroxide. Synthesised materials are confirmed by XRD and SEM analysis. The FTIR spectra of nanooxides have been analyzed in the frequency range of 400-4000cm-1.

Zinc ferrite (ZnFe2O4) nanocrystalline powder material was prepared by combustion method. The X-ray diffraction (XRD) and scanning electron microscopy (SEM) is used to study on structural properties. The magnetic properties of the sample were measured at room temperature using vibrating sample magnetometer (VSM) in the field range �15000 G. Hysteresis loop obtained room temperature for ZnFe2O4 nanoparticles indicates that the nanoparticles are ferromagnetic in nature.
