Description
Summary:Nanosized Mn<sub>3</sub>O<sub>4</sub> nanowires are prepared with KMnO<sub>4</sub> and ethanol in mild conditions by facile hydrothermal method. Hydrothermal reaction temperature is optimized to get uniform nanowires. The prepared Mn<sub>3</sub>O<sub>4</sub> nanowires exhibit high activity in the treatment of phenol at acid condition and room temperature. The 20 mg Mn<sub>3</sub>O<sub>4</sub> nanowires can efficiently dispose of 50 mL phenol solution (0.2 g&#183;L<sup>&#8722;1</sup>) at pH 2 and 25 &#176;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.
