The initial sticking probability of the reactive gases H2 and CO on
a nearly defect free Pt(111) surface is studied in the temperature
range 90�300 K by means of Thermal Energy Atom Scattering (TEAS).
By means of TEAS relative initial sticking probabilities can he measured
with great accuracy. H2/Pt(111): The initial sticking probability
is found to increase with increasing surface temperature. The important
role in the chemisorption process played by defects, even at concentrations
< 10-3 is emphasized. A two-stage model is proposed to explain these
results. CO/Pt(111): The initial sticking probability is found to
decrease with increasing surface temperature. This observation is
explained with a precursor model.
