dc.description.abstract	Isotopic exchange of oxygen from CO2 was used to study and characterize the lability of oxygen species at the surface of a catalyst. The catalysts were Pt supported on silica or alumina with several Pt loadings. Pt dispersion could be determined and was found to be in excellent agreement with oxygen-hydrogen titration and electron microscopy. Some surface oxygen species from the support and neighbouring Pt particles were made more labile. This indicates that interaction has occurred between Pt particles and the support, leading to more mobile surface oxygen which may be related to the spill-over effect.	en_US
