Synthesis and Characterization of Mn2[Fe (CN)6].xH2O Nanocomposites by Coprecipitation Method

Physics (NanoTechnology)

Nanocomposites of Mn2[Fe(CN)6]xH2O were achieved by using the materials like manganese chloride, FeCl3, and K3FeC6N6 in the form of a dilute solution with the help of a wet chemical Co-precipitation process. The crystal structure of the prepared sample was characterized by using XRD method and the surface morphology of prepared nanoparticles was characterized by FTIR spectroscopy. Quality results suggest that spherical shaped nano-composites of Mn2[Fe(CN)6]xH2O can be obtained. Thermal treatment of these compounds provides manganese ferrite (MnFe2O4) with defined grain boundaries. The size of the prepared nano-crystallites was 15-25 nm. Here, we observed the thermal change in the phase decomposition and the phase evolution of the ready sample. The outcomes from the characterization showed that the shape, phase and crystal structure of the nano-crystals were strongly changed. Besides, the direct phase transition from Manganese Iron Cyanide Hydrate Mn2[Fe(CN)6]xH2O to MnFe2O4 occurred at 300°C for 3houres. The overall size of the finally obtained product i.e. MnFe2O4 (manganese ferrite) is approximately 25 nm.
