| Popis: | The chemisorbed species formed by reaction of nitrogen-containing gases (NO, N 2 O, N 2 and dry air) on some transition metals (Ni, Cu, Ti, Co and Pd) at high pressures (1–200 torr) are examined by XPS. At least four adsorption species are observed on the surface at ambient temperature. They can be assigned to −NO 3 (407.3 eV), −NO 2 (404.5 eV), −NO (400.0 eV) and the nitrogen bound directly to metal, which shows a characteristic energy value for each metal. This feature differs from the reported results of low pressure adsorption experiments. Relative abundances among the chemisorbed species vary with individual metals and gases. |
