| Abstract: | On basis of the redox reaction between MnO4− and Mn2+, a facile hydrothermal method combined with the adjustment of pH value in the reaction system has been employed to synthesize single-crystal γ-MnOOH nanorods, and square-like Mn3O4 nanoparticles. Additionally, single-crystalline β-MnO2 and Mn2O3 nanorods can be obtained after subsequent calcinations of the as-prepared γ-MnOOH nanostructures at 300 °C and 600 °C, respectively. Furthermore, electrochemical property of as-obtained β-MnO2 is also studied. |
