Low Temperature Hydrothermal Synthesis of 3D-MnO2 Nanostructures and their Catalytic Properties over MB

Abstract

A novel three-dimensional MnO2 catalyst have been successfully prepared by a facile hydrothermal route. They were characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM). In addition, they showed excellent catalytic activity over the aqueous degradation of methylene blue (MB).
