Abstract:
The desorption and dissociation of oxygen admolecules were studied on a stepped Pt(533) surface by using thermal desorption combined with an isotope tracer. The desorption from the molecular adsorption state yields two main peaks at 145 and 225 K. The latter peak is assigned to desorption from step sites. Most of the admolecules on step sites dissociate into adatoms in the subsequent heating in the range of 150-250 K, whereas admolecules on terraces desorb to a large extent without dissociation.
