| 摘 要： | 采用简单的水热法,通过控制不同锰源、酸碱性及水热温度等条件制备一系列MnO_2催化剂,利用SEM、XRD、N_2吸附-脱附和H_2-TPR等对MnO_2催化剂的物化性能进行表征,考察MnO_2催化剂催化炭烟颗粒燃烧的性能。结果表明,制备的纳米棒状MnO_2催化剂均具有良好的催化燃烧炭烟活性,在水热温度120℃、锰源为硝酸锰和酸性条件下,制备的MnO_2催化剂具有最佳催化燃烧炭烟颗粒的性能。

| Abstract: | A series of MnO2 catalysts were prepared by simple hydrothermal method by changing manganese sources,hydrothermal temperatures and pH values.The physicochemical properties of MnO2 catalyst were characterized by means of SEM,XRD,N2 adsorption-desorption,H2-TPR and so on.The catalytic performance of MnO2 catalysts for soot combustion was investigated.Results indicated that all nanorod-shaped MnO2 catalysts had excellent catalytic activity for soot particles combustion.When hydrothermal temperature was 120 ℃,manganese source was manganese nitrate and reaction system was acidic conditions,MnO2 catalyst exhibited the best catalytic performance for soot particles combustion among the as-prepared catalysts. |
