Controllable Synthesis of Birnessite-Based Manganese Oxide Nanostructures

Article Preview

Abstract:

Layered manganese oxide nanostructures were synthesized by a facile hydrothermal method, using KMnO4 and CH3CH2OH as the precursors. The structure, composition and morphology of the product are evaluated by means of X-ray diffraction (XRD), scanning electron microscopy (SEM) and Infrared (IR) techniques. The results showed that crystalline birnessite-based manganese oxide was formed and the hydrothermal time and temperature had great influence on nanostructures of the products. The electrochemical results showed that birnessite nanowires exhibit excellent cyclic stability performance in the potential application window of 1.5~4.8 V.
