The product analysis indicates a selectivity of the polycrystalline gold towards formation of acetaldehyde. The oxidation process on fresh surface prepared by surface gold oxide reduction, on the other hand, forms mainly carbon dioxide. The oxidation process encompasses metal dissolution. DFT based analysis of the ethylene oxidation on Au clusters was employed to interpret the experimental data. DFT calculations support experimental findings and indicate possible reaction mechanisms of catalytic reactions. DFT calculations point to the different reactivity on individual types of surfaces and different types of clusters.
