CATALYTIC PROPERTIES OF SURFACES SITES ON METAL OXIDES AND THEIR CHARACTERIZATION BY X-RAY PHOTO-ELECTRON SPECTROSCOPY

摘要

The long range objective;of this research program is to modify the distribution of oxidation states which are stable at the surface of a metal oxide catalyst by controlling the dispersion of the catalyst on its inert support. The catalytic activity and selectivity of the catalyst will then be correlated against the oxidation state of the surface sites which will be measured using x-ray photoelectron spectroscopy.
