Morphology Control of the Nano-MnO₂ by Microwave Hydrothermal Synthesis

Abstract:

In this paper, KMnO₄ was used as raw material, nano-MnO₂ with different morphologies such as flowers globular, hollow tubular and rodlike were obtained by the microwave assisted hydrothermal synthesis under the acidic condition. The crystal structure and morphology of the resultant MnO₂ were characterized by X-ray Diffraction (XRD) and Scanning Electron Microscope (SEM), respectively. The elements and content of samples were tested by Energy Dispersive Spectrometer (EDS). The influence of reaction temperature and holding time on crystal forms and morphologies of the MnO₂ was analyzed.
