The results reported highlight the great potential of the use of size-tunable preformed AuNPs for the preparation of active catalysts. The use of preformed metal clusters and the mild reaction conditions are not favorable to the formation of ionic Au species. The experimental results suggest that the catalytic sites for CO oxidation are the metal NPs and not ionic Au species.

Abstract
The results reported highlight the great potential of the use of size-tunable preformed AuNPs for the preparation of active catalysts. The use of preformed metal clusters and the mild reaction conditions are not favorable to the formation of ionic Au species. The experimental results suggest that the catalytic sites for CO oxidation are the metal NPs and not ionic Au species.File in questo prodotto:
