dc.description.abstract [EN] Gold nanoparticles smaller than similar to 2 nm show interesting catalytic properties arising from their size-determined electronic and geometrical structures. They are able to dissociate molecular O-2 with low activation barriers and become oxidized in a reversible way at low temperature. Several oxygen species adsorbed on the nanoparticle surface, as well as different gold sites including low coordinated neutral Au-0 atoms and cationic Au-I and Au delta+ species, are generated on the oxidized nanoparticles. The implication of these new sites in the mechanism of different gold-catalyzed reactions in which oxygen plays a crucial role is discussed here. es_ES
