Synthesis and Characterization Nano Structure of MnO2 via Chemical Method


In the current research, Magnesium oxide II (MnO2) nanostructures were prepared by chemical route from hydro manganese chloride salt using Potassium hydroxide as reducing agent. X-Ray diffraction (XRD), SEM and Fourier transformation infrared (FTIR) used to characterize both particle size and structure of MnO2 nanoparticles. XRD results confirmed impurity of synthesized powder with α-MnO2 as predominant phase. The average particle size of manganese dioxide was in the range 25- 30 nm. Photographs of scanning electron microscope (SEM) showed two hierarchical structures, cluster agglomeration and chain appearance.
