Adsorption properties and vibrational spectra of propyne adsorbed on Rh(111). Comparison with other (111) metal surfaces

Abstract

We have studied the adsorption properties of propyne on the Rh(111) surface by means of the generalized gradient approach of density functional theory using periodic slab models. The simulation of the vibrational spectra has permitted us to corroborate and complete the experimental band assignment and to confirm the adsorption site preference. Propyne prefers to sit on a 3-fold hollow site, with the C[triple bond, length as m-dash]C axis parallel to a Rh–Rh bond and the molecular plane tilted away from the surface normal. The comparison between the adsorption behaviour of propyne on Rh(111) and on other (111) metal surfaces allows one to provide an explanation for the different reactivity observed experimentally.
