Description
Summary:Nanosized Mn O nanowires are prepared with KMnO and ethanol in mild conditions by facile hydrothermal method. Hydrothermal reaction temperature is optimized to get uniform nanowires. The prepared Mn O nanowires exhibit high activity in the treatment of phenol at acid condition and room temperature. The 20 mg Mn O nanowires can efficiently dispose of 50 mL phenol solution (0.2 g·L ) at pH 2 and 25 °C. The nanowires before and after phenol treatment are characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS) and the reaction mechanism is discussed.
