摘要：

Single-crystalline alpha-MnO2 nanorods have been prepared by reducing KMnO4 with graphite in concentrated H2SO4 solution at 0 degrees C. Hydrothermal treatment of the alpha-MnO2 nanorods at 100 degrees C results in the formation of single-phase gamma-MnOOH nanorods. The structure and morphology of the alpha-MnO2 and gamma-MnOOH are characterized with X-ray diffraction (XRD), transmission electron microscopy (TEM) and Fourier transformed infrared (FTIR) spectroscopy, respectively.
