AbstractThe interaction of supported vanadium oxide with Al2O3 and TiO2 substrates is examined with Raman spectroscopy. The Raman spectra of the supported vanadium oxide reveal that the strong interaction of the vanadium oxide with the Al2O3 and TiO2 supports results in the formation of an atomically dispersed surface vanadium oxide phase as well as supported crystalline V2O5. The relative concentrations of the atomically dispersed surface vanadium oxide and crystalline V2O5 depend on the vanadium oxide loading and the surface area of the oxide support.
