Hydrothermal Synthesis of α-MnO₂ Nanostructures at Low Temperature and their Electrochemistry Properties

Abstract

A novel three-dimensional MnO2 have been successfully prepared by a facile hydrothermal route without any catalysts below 90oC. They were characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM). In addition, the obtained α-MnO2 nanorods showed excellent capacitive behavior, cyclic voltammograms stability and favorable electronic conductivity.
