| 摘 要： | The adsorption of nitric oxide adsorption on clean Mod(111), Mo(111)/O2-(4×4), Mo(111)/O2-(1×3), Mo(111)/O2-(112) facets and Mo(111) oxide surfaces was studied. Mass 28 (N2) desorption spectra show two high temperature peaks at approximate 1030 (β1) and 1200K (β2). For NO exposures less than 0. 1 L only the ft peak was observed. At higher exposures, the ft peak appeared and small amounts of N2O as well as NO desorbed. The preadsorption of oxygen blocked the β2 desorption partially on the (4×4) and (1×3) surfaces and fully on the (112) facet and oxide surfaces. In addition, the β1 desorption peak shifted to higher temperatures with increasing oxygen preexposure.
