Activity and Selectivity of Size-Selected Sub-nm to Nanometer Size Silver Clusters in the Selective Oxidation of Propylene
ORAL
Abstract
The activity and selectivity of Ag nanoparticles in propene oxidation will be discussed and compared with the performance of Ag3 clusters. The experimental studies are based on 1) chemically uniform support fabrication, 2) size-selected cluster deposition, 3) electron microscopy of nanoclusters, and 4) in situ synchrotron X-ray characterization of clusters under working conditions, combined with mass spectroscopy analysis of reaction products.
