摘要：

Acetaldehyde oxidation at Pt(111) and Pt(100) follows at least two parallel reaction pathways leading to CO2 and acetic acid as soluble products. The former is produced via strongly adsorbed intermediates. Besides adsorbed CO, also species containing two C atoms, possibly eta(1)-acetaldehyde and eta(1)-acetyl, are formed. These species are strongly bonded to the surface. None of these adsorbates are the intermediate leading to the formation of acetic acid.
