| 摘要: 采用水热法制备出不同金属离子Mn+（Mn+=Co2+，Cu2+，Fe3+，Al3+，Ce4+）掺杂的δ-MnO2催化剂，简称MMn，用于氯苯催化氧化。通过X射线衍射（XRD）、扫描电子显微镜（SEM）、透射电子显微镜（TEM）、氮气吸附-脱附、X射线光电子能谱（XPS）、程序升温还原（H2-TPR）等手段对催化剂进行了表征。结果表明，相同反应条件下，对氯苯的催化效率比较结果为：AlMn > FeMn > CeMn > CuMn > δ-MnO2 > CoMn。Al改性δ-MnO2催化剂较高的比表面积，较低的可还原温度和较多的表面活性氧Osur是具有较高催化活性的重要因素。 |

| Abstract: The δ-MnO2 catalysts doped with different metal ions Mn+ (Mn+=Co2+, Cu2+, Fe3+, Al3+, Ce4+) were prepared by hydrothermal method, which was referred to as MMn for catalytic oxidation of chlorobenzene. The catalysts were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), N2 absorption-desorption, X-ray photoelectron spectroscopy (XPS) and temperature-programmed reduction (H2-TPR). The results showed that the catalytic efficiency of chlorobenzene under the same reaction conditions was:AlMn > FeMn > CeMn > CuMn > δ-MnO2 > CoMn. The higher specific surface area, the lower reducible temperature and more surface active oxygen Osur of Al-doped δ-MnO2 catalyst are important factors for higher catalytic activity. |
