本文利用光电子能谱（ＸＰＳ和ＵＰＳ）技术研究了室温ＴＯ２和Ｒｂ在ＩｎＳｂ（１１１）表面上共吸附，分析了碱金属Ｒｂ在ＩｎＳｂ（１１１）表面上吸附的健合状态以及对衬底的催化氢化作用。结果表明，Ｒｂ与ＩｎＳｂ表面上的Ｓｂ发生化学反应，Ｒｂ在ＩｎＳｂ表面上吸附提高了衬底表面的氧化速率，衬底表面上的Ｉｎ和Ｓｂ被氧化，分别生成锑和铟的氧化物。在Ｏ２吸附的过程中，还观察到两种Ｒｂ的氧化物，即过氧化铷（Ｒｂ２Ｏ２）和超氧化铷（ＲｂＯ２）。通过芯能级和价电子的变化，揭示了各种氧离子态（Ｏ２－，Ｏ，Ｏ）的形成。 In this paper, the co-adsorption of TO2 and Rb on the InSb (111) surface has been studied by using photoelectron spectroscopy (XPS and UPS). The adsorption state of Rb on the InSb (111) Hydrogenation. The results show that Rb chemically reacts with Sb on the surface of InSb. The adsorption of Rb on the surface of InSb increases the oxidation rate on the surface of the substrate. In and Sb on the surface of the substrate are oxidized to produce oxides of antimony and indium, respectively. Two oxides of Rb, rubidium peroxides (Rb2O2) and rubidium peroxides (RbO2), were also observed during the O2 adsorption. Through the changes of the energy levels and valence electrons, the formation of various oxygen ion states (O2-, O, O) is revealed.
