Nanosized MnO 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 MnO nanowires exhibit high activity in the treatment of phenol at acid condition and room temperature. The 20 mg MnO 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.
通过简便的水热法，在温和条件下用高锰酸钾和乙醇制备了纳米级二氧化锰纳米线。优化水热反应温度以获得均匀的纳米线。所制备的二氧化锰纳米线在酸性条件和室温下处理苯酚时表现出高活性。20毫克二氧化锰纳米线在pH值为2和25℃时能有效处理50毫升苯酚溶液（0.2克·升）。通过扫描电子显微镜（SEM）、X射线衍射（XRD）和X射线光电子能谱（XPS）对苯酚处理前后的纳米线进行了表征，并讨论了反应机理。
