Title:
Chemical reactions on size-selected clusters on surfaces 
Abstract:
Cluster-assembled materials open fascinating new routes for tuning phys. and chem. properties by changing cluster size and often these materials behave completely differently than their bulk analogs. By depositing gas phase cluster cations on various surfaces, cluster model catalysts are fabricated, which exhibit remarkable catalytic activity. While inert as bulk material, gold cluster catalysts oxidize carbon monoxide with Au8 to be the smallest active size. In contrast to the high selectivity...    »
