Abstract

XPS, HREELS, ARUPS and Δφ data show that furan chemisorbs non-dissociatively on Pd{111} at 175 K, the molecular plane being significantly tilted with respect to the surface normal. Bonding involves both the oxygen lone pair and significant π interaction with the substrate. The degree of decomposition that accompanies molecular desorption is a strong function of coverage: ∼40% of the adsorbate desorbs molecularly from the saturated monolayer. Decomposition occurs via decarbonylation to yield CO_a and H_a followed by desorption rate limited loss of H₂ and CO. It seems probable that an adsorbed C₃H₃ species formed during this process undergoes subsequent stepwise dehydrogenation ultimately yielding H₂ and C_a.
