Synthesis of Monodisperse Fe₃O₄ and MnFe₂O₄ Nanospheres by Using a Solvothermal Reduction Method

Abstract:

The spinel ferrites, MFe₂O₄ (where M=Fe, Mn, Co, Ni, Zn, Mg, etc.) have attracted considerable interest during the last few decades due to their potential applications in high frequency transformers, filters, high density storage devices, and microwave applications. In the latest several years, many synthesis technologies such as sol-gel, auto-combustion, thermal decomposition methods and hydrothermal reaction have been developed to prepare spinel ferrite nanoparticles. In this paper, the spinel ferrites Fe₃O₄ and MnFe₂O₄ nanoparticles were synthesized by using a solvothermal reduction method. X-ray diffraction (XRD) and Raman analysis shows that all the peaks are close to the data for Fe₃O₄ and MnFe₂O₄, indicating the prepared particles are single phase. The scan electronic microscopy (SEM) shows that the prepared Fe₃O₄ and MnFe₂O₄ are monodisperse nanospheres and with the average size of around 300nm.
