Abstract  

 A niobium oxide thin film was obtained by oxidizing Nb(110). UPS was used to characterize the adsorption of methanol, water and ethylene on this film at different temperatures. The results show that at 140K, methanol and water chemisorb associatively at all coverages, while ethylene chemisorbs at low coverages and physisorbs at high coverages. At 300K, these molecules adsorb dissociativelly. The adsorption on surface defect centers is stronger: molecules are adsorbed on these sites first, and are also more affected by the adsorption. Nb5+ is the main adsorption centers on the surface, but oxygen ions on the surface are also adsorption centers.
