On-Surface Carbon Nitride Growth from Polymerization of 2,5,8-Triazido-s-heptazine
Matthias Krinninger, Nicolas Bock, Sebastian Kaiser +8
Carbon nitrides have recently come into focus for photo- and thermal catalysis, both as support materials for metal nanoparticles as well as photocatalysts themselves. While many a…
Does cluster encapsulation inhibit sintering? Stabilization of size-selected Pt clusters on FeO(001) by SMSI
Sebastian Kaiser, Johanna Plansky, Matthias Krinninger +5
The metastability of supported metal nanoparticles limits their application in heterogeneous catalysis at elevated temperatures due to their tendency to sinter. One strategy to ove…
Tuning SMSI Kinetics on Pt-loaded TiO(110) by Choosing the Pressure: A Combined UHV / Near-Ambient Pressure XPS Study
Philip Petzoldt, Moritz Eder, Sonia Mackewicz +6
Pt catalyst particles on reducible oxide supports often change their activity significantly at elevated temperatures due to the strong metal-support interaction (SMSI), which induc…
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…
CO oxidation on a single Pd atom supported on magnesia
S. Abbet, U. Heiz, H. Hakkinen +1
The oxidation of CO on single Pd atoms anchored to MgO(100) surface oxygen vacancies is studied with temperature-programmed-reaction mass-spectrometry and infrared spectroscopy. In…
