The sticking probability and heat of adsorption for C2H4 on the stepped
Pt211 and Pt311-(1x2) surfaces have been measured for the first
time. Adsorption on Pt211 leads to the formation of several different
species as a function of coverage, whereas adsorption on Pt311-(1x2)
leads to the formation of only one species on the surface over the
whole coverage range. The initial heats of adsorption for C2H4 on
Pt211 and Pt311-(1x2) have been measured as 180 and 220kJmol-1,
respectively. The initial sticking probabilities are 0.84 for both
surfaces. The most likely species to be formed on Pt211 as a function
of coverage are quad-sigma acetylene followed by ethylidyne whereas
on Pt311-(1x2) ethylylidyne forms at all coverages.
