Synthesis and characterization of nanoparticle BaFe2O4 using precursor [Fe(bpy)3]2[Ba(acac)2(SCN)2 (H2O)2]

In this investigation, we report a new nanostructured was prepared from cationic-anionic complex of formula [Fe(bpy)3]2[Ba(acac)2(SCN)2 (H2O)2] (bpy= 2 2 -bipyridine, acac=Acetylacetone).The complex has been characterized by FT-IR, UV-Vis, conductivity measurements, elemental analysis and cyclic voltammetry (CV) method for electrochemical studies. The infrared spectroscopy results showed that bpy ligand connected to metal center by two nitrogen atomes of bpy[1]. Vibration frequencies in the region of 2052 cm-1 (NCS-stretching) and 843cm-1 (CS- stretching) confirmed that, the NCS ligand connect to metal center through nitrogen atom. Also, in this study, barium- iron nano-oxid BaFe2O4 are prepared from the complex [Fe(bpy)3]2[Ba(acac)2(SCN)2 (H2O)2] at 750°C. The nanoparticles was investigated using FT-IR, XRD (X-Ray Diffraction), SEM (Scanning Electron Microscopy), and EDX (Energy Dispersive X ray). XRD results all peaks in the XRD pattern were identified as belonging to BaFe2O4. The average size of the particles is 14.1 nm. In SEM image, it was observed that the nanoparticles with the same morphology had a uniform porous surface. The percentages of the components were obtained through EDX.
