Cluster Catalysis with Lattice Oxygen: Tracing Oxygen Transport from a Magnetite(001) Support onto Small Pt Clusters
Sebastian Kaiser, Farahnaz Maleki, Ke Zhang +6
Oxidation catalysis on reducible oxide-supported small metal clusters often involves lattice oxygen. In the present work, we trace the path of lattice oxygen from Fe3O4(001) onto s…

Influence of Local Defects on the Dynamics of O-H Bond Breaking and Formation on a Magnetite Surface
Alexander Bourgund, Barbara A. J. Lechner, Matthias Meier +4
The transport of H adatoms across oxide supports plays an important role in many catalytic reactions. We investigate the dynamics of H/Fe3O4(001) between 295 and 382 K. By scanning…

A Microscopy Approach to Investigating the Energetics of Small Supported Metal Clusters
Barbara A. J. Lechner, Fabian Knoller, Alexander Bourgund +2
Metal clusters are partway between molecular and bulk systems and thus exhibit special physical and chemical properties. Atoms can rearrange within a cluster to form different stru…
