摘要

采用水热法制备出不同金属离子M~(n+)(M~(n+)=Co~(2+),Cu~(2+),Fe~(3+),Al~(3+),Ce~(4+))掺杂的δ-MnO_2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(H_2-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-MnO_2>CoMn。Al改性δ-MnO_2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O_(sur)是具有较高催化活性的重要因素。
        The δ-MnO_2 catalysts doped with different metal ions M~(n+)(M~(n+)=Co~(2+), Cu~(2+), Fe~(3+), Al~(3+), Ce~(4+)) 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), N_2 absorption-desorption, X-ray photoelectron spectroscopy(XPS) and temperature-programmed reduction(H_2-TPR). The results showed that the catalytic efficiency of chlorobenzene under the same reaction conditions was: Al Mn > FeMn > CeMn > Cu Mn > δ-MnO_2> CoMn. The higher specific surface area, the lower reducible temperature and more surface active oxygen Osurof Al-doped δ-MnO_2 catalyst are important factors for higher catalytic activity.
