摘要：

Three V2O5/TiO2 samples were investigated by members of the 'oxide group' of the Eurocat project by means of electron microscopic techniques. The bare support consisted of well crystallized TiO2 particles. No crystalline V2O5 could be observed in the 1% V2O5/TiO2 (EL10V1) catalyst, indicating a good dispersion of the active phase. The 8% V2O5/TiO2 (EL10V8) catalyst exhibited substantial inhomogeneities, viz. enrichment of the vanadium in parts of the external edge of the TiO2 CryStallites, and unsupported V2O5 platelets. Prolonged exposure of the samples to the electron beam caused damage to the oxide lattice, which transformed into a suboxide.
