In latest years, Manganeseoxide nanoparticles (MnO2 NPs) have intrigued material science research are widely owing an extensive variety of application. In this study, the roll of metal precursor in the production of Manganese Oxide nanoparticle has been studied. The manganese oxide nanoparticles were prepared by using manganese chloride hexhydrates salts. To get samples and characterization studied through X-ray diffraction (XRD), UV-visble absorbance HR-SEM and Elemental analysis spectroscopy (EDAX). The XRD indicates that the prepared nanoparticles are crystalline in nature with tetragonal structure. UV exhibits the prepared manganese oxide were nanoparticles in the wavenumber ranges of 391.73cm-1 .The HR SEM images revealed typical 2Ddeposit sheet-like morphologies with multiple folds for non-intercalated MnO2 whereas intercalated MnO2 showed more flattered and planar shaped.
