Abstract:
In the current study, partial oxidation of acetaldehyde on oxygen pre-covered Au(111) single crystal model catalyst surface has been investigated. It has been demonstrated that for low oxygen coverages, two different partial oxidation products namely, methyl acetate and acetic acid can be generated without the formation of significant quantities of carbon dioxide. Since the formation of methyl acetate as the oxidative coupling reaction product implies C-C bond cleavage; it was demonstrated that oxygen pre-covered Au(111) single crystal model catalyst surface can activate C-C bonds. In addition to the generation of these products; indications of the polymerization of acetaldehyde on the gold surface were also observed as an additional catalytic route competing with the partial and total oxidation pathways. The interplay between the partial oxidation, total oxidation and polymerization pathways reveals the complex catalytic chemistry associated with the interaction between the acetaldehyde and atomic oxygen on the gold catalyst surfaces
