Low-Temperature Cluster Catalysis

Free and supported metal clusters reveal unique chem. and phys. properties, which vary as a function of size as each cluster possesses a characteristic electron confinement. Several previous exptl. results showed that the outcome of a given chem. reaction can be controlled by tuning the cluster size. However, none of the examples indicate that clusters prepd. in the gas phase and then deposited on a support material are indeed catalytically active over several reaction cycles nor that their catalytic properties remain const. during such a catalytic process. In this work we report turn-over frequencies (TOF) for Pdn (     «
