The sticking probability and heat of adsorption for C2H4 on the stepped Pt(211) and Pt(311)-(1 x 2) surfaces have been measured for the first time. Adsorption on Pt(211) leads to the formation of several different species as a function of coverage, whereas adsorption on Pt(311)-(1 x 2) leads to the formation of only one species on the surface over the whole coverage range. The initial heats of adsorption for C-2,H-4 on Pt(211) and Pt(311)-(1 x 2) have been measured as 180 and 220 kJ mol(-1), respectively. The initial sticking probabilities are 0.84 for both surfaces. The most likely species to be formed on Pt(211) as a function of coverage are quad-a acetylene followed by ethylidyne whereas on Pt(311)-(1 x 2) ethylylidyne forms at all coverages.
