Simple hydrothermal preparation of γ-MnOOH nanowires and their low-temperature thermal conversion to β-MnO2 nanowires
چکیده انگلیسی
Without the use of any extra surfactant or template, γ-MnOOH single crystalline nanowires were synthesized directly through the hydrothermal reaction between KMnO4 and toluene in distilled water at 180 °C for 24 h; and β-MnO2 single crystalline nanowires could be obtained just by calcination of the γ-MnOOH nanowires in air at 280 °C for 5 h. The as-prepared γ-MnOOH and β-MnO2 nanowires were characterized by X-ray powder diffraction, atomic absorption spectroscopy, Fourier transformed infrared spectroscopy, scanning electron microscope, transmission electron microscope, high-resolution transmission electron microscope and selected area electron diffraction.
