| 摘 要： | 以SiO_2为载体,采用等体积浸渍法制备了极低负载量活性组分氧化物催化剂,并评价对丙烷选择氧化性能。结果表明,在对丙烷分子氧选择氧化催化反应中,具有相对稳定半充满电子的表面离子结构的催化剂对生成醛类含氧化合物选择性较高。碱金属钾的修饰作用使含氧化合物选择性有较大提高。

| Abstract: | A series of supported transition metal oxide catalysts wlm ultra-low loaalng oi umcrcm active components were prepared by inc selective oxidation loading of different of propane was ipient-wet impregnation method. Their catalytic performance for the investigated. The results showed that M/Si02 catalysts with ultra-low active components,which had the stable ion configuration with half-full electron struc- ture, exhibited higher selectivity for the oxidation of propane to aldehydes. The activity and selectivity of the catalysts were greatly enhanced by the addition of potassium. |
