摘要：

IR and Raman spectroscopic studies show that the catalyst EL10V1 consists of a 'monolayer' of surface vanadyl complexes spread on the TiO2 support surface. Such a 'monolayer' contains both Lewis and Bronsted acidic sites, while the nucleophilic sites of the support surface are suppressed. On the catalyst EL10V8, V2O5 particles are also present. UV-Vis spectra show that V5+ is predominant on the calcined catalysts; part of it can be converted easily into V4+. Evidence is also found for electronic interaction between the support and the surface vanadium oxide species.
