中文摘要:
      采用XRD,XPS技术,研究了PdO在不同类型载体上的分散形式,表面物种状态,所得的结果与CO氧化反应相关联。结果表明,载体对活性组分的表面结构组成,分散度大小的影响是导致催化性能不同的主要因素。
英文摘要:
      The surface species and dispersion state of PdO on different kinds of support were studied by means of XRD and XPS technique. The oxidative activity of catalysts for CO and CH 4 were also examined. The results showed that the effect of the support to the surface component and crystal structure are the main cause of the great difference in catalytic activity.
