Abstract

The surface compounds Pt–O and Pt–H were studied by means of soft X-ray spectroscopy using a variety of supported Pt-catalysts. Unexpectedly large chemical shifts were observed in the M-series, amounting for certain bands to as much as +7 and -27 eV with respect to bulk platinum. Other M-bands remain virtually unchanged. The intensity of the shifted bands can be correlated with the degree of dispersion. A model based on surface molecular orbitals will be discussed.
