| 英文摘要 | Three types of thin films of niobium oxide on Pt(111): NbOx, Nb2O5 and Ar+-bombarded Nb2O5 were studied. The thin films were made up of a high density of small crystallites on an epitaxial monolayer. AES, ILS and UPS showed that the NbOx thin film had an electronic structure that is a composite of those of NbO, NbO2 and Nb2O5, while the Nb2O5 thin film had an electronic structure similar to Nb2O5. LEED and HREELS showed that the surface periodicities and crystal structures differ from those of the bulk oxides. HREELS indicates a structural similarity with some supported two-dimensional Nb oxide monolayers with Nb=O surface sites of highly distorted NbO6 octahedra. Ar+ bombardment decreased the proportion of surface oxygen. Water adsorption at room temperature, studied by HREELS and UPS, was associative on Nb2O5 and dissociative on Ar+-bombarded Nb2O5. It was associative on NbOx but dissociates on heating. |
