Abstract
A structural-controlled synthesis of manganese oxide nanostructures from single Mn3O4 precursor via hydrothermal method is presented. The obtained products include α- andβ-MnO2 nanorods, γ-MnO2 urchin-like microspheres, birnessite nanowires and nanosheets. The morphology evolution process and the effect of varying reaction parameter to the phase and morphology are systematically investigated. The formation mechanisms have been rationalized. The obtained nanostructures are as the model system for studying the electrochemical capacitance performances, which have been investigated by cyclic voltammetry.
