Abstract
Manganese dioxides with various morphologies were prepared using a common hydrothermalmethod without any templates or additives. The evolution of the morphology was accompanied by the gradual conversion of the polymorphic forms from γ-type to β-type. Meanwhile, MnO2 microspheres, urchin-like nanostructures and nanowires were successfully synthesized. The products were characterized by X-ray diffraction, X-ray photoelectron spectroscopy, scanning electron microscope and transmission electron microscope. The evolution process can be explained by the Ostwald Ripening mechanism.
