Abstract

   In the present work Mn3O4 nanoparticles (NPs) with spinel structure were synthesized successfully via combustion route with MnIII(acac)3 as precursor in two different temperatures. The morphology of the synthesized Mn3O4 were investigated by field emission scanning electron microscope (FESEM) and structural analysis was studied by powder X-ray diffraction (PXRD) technique that it indicated that the Mn3O4 nanoparticles with space group of l41/amd Structural analysis was performed by fullprof program employing profile matching with constant scale factors. The lattice parameters for both samples were found a = b = 5.7621 Å and c= 9.4696 Å, α = β = γ = 90°. In addition, the size of the Mn3O4 nanoparticles obtained from the Transmission Electron Microscopy (TEM) that the average is 20 nm. Magnetic property of synthesized Mn3O4 was done by Vibration Sampling Magnetometer (VSM) that confirm the paramagnetic behavior. The optical properties of the obtained materials were investigated by Furrier-Transform Infrared spectroscopy (FTIR) and Ultraviolet-Visible spectrum (UV-Vis). The thermal stability was determined by Thermo Gravimetric Analysis (TGA).
