dc.description.abstract | [EN] The mechanism of the CO oxidation reaction catalysed by planar Cu-5, three dimensional (3D) Cu-5, and 3D Cu-8 clusters is theoretically investigated at the B3PW91/Def2TZVP level. All three clusters are able to catalyse the reaction with similar activation energies for the rate determining step, about 16-18 kcal mol(-1), but with remarkable differences in the reaction mechanism depending on cluster morphology. Thus, for 3D Cu-5 and Cu-8 clusters, O-2 dissociation is the first step of the mechanism, followed by two consecutive CO + O reaction steps, the second one being rate determining. In contrast, on planar Cu-5 the reaction starts with the formation of an OOCO intermediate in what constitutes the rate determining step. The O-O bond is broken in a second step, releasing the first CO2 and leaving one bi-coordinately adsorbed O atom which reacts with CO following an Eley-Rideal mechanism with a low activation energy, in contrast to the higher barriers obtained for this step on 3D clusters. | es_ES |
