Abstract:
129Xe NMR spectroscopy was used to study xenon adsorption on V2O5/TiO2/SiO2 catalysts with varying ratio of supported vanadia and titania components. These catalysts were chosen because of their strong electron-accepting (Lewis) acidity. Xenon atoms despite their large polarizability exhibit weak basic properties. The specific interactions of adsorbed xenon atoms with the strongest Lewis acidic sites were detected with 129Xe NMR. It was demonstrated that a possibility of such interactions should be taken properly into account when studying porous solids by the adsorption of gaseous xenon.
