Sonochemical-Assisted Coprecipitation Synthesis of Body-Centered Tetragonal Mn3O4 Spinel Nanostructures Using Polyethylene Glycol Template Agent

[摘要] The excellent characteristics of Mn3O4 nanomaterials have driven many experts to carry on exploring improved approaches for Mn3O4 fabrication. Herein, Mn3O4 nanostructures have been synthesized via sonochemical-assisted coprecipitation method. Polyethylene glycol (PEG-6000) with various concentrations was employed as a surface coating. The combination of coprecipitation and ultrasonication has led to the formation of Mn3O4 nanoparticles which were well-confirmed by three different characterization instruments, i.e., X-ray diffraction (XRD), scanning electron microscopy (SEM) along with energy dispersive X-ray (SEM-EDX), and Fourier transform infrared (FTIR). The XRD data collection and analysis reveal the presence of single-phase of Mn3O4 spinels. The Rietveld refinement dictates the establishment of tetragonal distortion along the c-axis creating a body-centered tetragonal spinel structure with a space group of I41/AMDS. In addition, the SEM-EDX and FTIR data support the experimental results obtained by XRD.
