摘要
利用浸渍法制备了Pd/Al2O3催化剂,采用X射线衍射(XRD)、透射电子显微镜(TEM)和X射线光电子能谱(XPS)研究了Pd在载体Al2O3中的分布状态和价态.结果表明纳米尺寸的Pd颗粒主要以单质形式高度分散在载体Al2O3上,部分呈氧化态.
Pd/Al2O3 catalysts were prepared by dipping method. The distribution and state of Pd particles on Al2O3 were investigated by TEM and XPS. The results show that nano--scale Pd particles highly dispersed on the surface of the support in the form of simple substance and partly have a positive oxidation state.
