XPS STUDIES OF SURFACE NITROGEN DISSOCIATED FROM DINITROGEN ON RANEY RUTHENIUM

Abstract
Atomic nitrogen species on Raney-Ru was studied by means of XPS in connection with isotopic equilibration reaction. Binding energy of a main N ls peak stable up to 673 K was 397.4 eV, which was assigned to be N(a). When the adsorbed nitrogen was heated from 673 K to 873 K under hydrogen atmosphere, the value shifted to 396.7 eV suggesting the formation of aluminum nitride.
