Abstract: A versatile hydrothermal reaction between KMnO4 and ascorbic acid(AA) was developed to synthesize manganese compounds. A variety of nanostructured manganese oxides including Mn3O4 nanoparticles, MnOOH, α-MnO2 and β-MnO2 nanorods have been prepared through adjusting the molar ratio of the reactants, pH value of the aqueous solution, reaction temperature and reaction time. The products were characterized by X-ray powder diffraction(XRD) and transmission electron microscopy(TEM). The possible reaction mechanism was discussed. |
Keywords: Hydrothermal method nanostructured manganese oxides redox reaction mechanism |
