CO oxidation by Pt2/Fe3O4: metastable dimer and support configurations facilitate lattice oxygen extraction
Matthias Meier, Jan Hulva, Zdenek Jakub +8
Heterogeneous catalysts based on sub-nanometer metal clusters often exhibit strongly size-dependent properties, and the addition or removal of a single atom can make all the differ…
Single Rh adatoms stabilized on α-Fe2O3(1-102) by co-adsorbed water
Florian Kraushofer, Lena Haager, Moritz Eder +8
Oxide-supported single-atom catalysts are commonly modelled as a metal atom substituting surface cation sites in a low-index surface. Adatoms with dangling bonds will inevitably co…
Rapid oxygen exchange between hematite and water vapor
Zdenek Jakub, Matthias Meier, Florian Kraushofer +6
Oxygen exchange at oxide/liquid and oxide/gas interfaces is important in technology and environmental studies, as it is closely linked to both catalytic activity and material degra…
Surface Reduction State Determines Stabilization and Incorporation of Rh on α-Fe2O3(1-102)
Florian Kraushofer, Nikolaus Resch, Moritz Eder +9
Iron oxides (FeOx) are among the most common support materials utilized in single atom catalysis. The support is nominally Fe2O3, but strongly reductive treatments are usually appl…
Unravelling CO adsorption on model single-atom catalysts
Jan Hulva, Matthias Meier, Roland Bliem +6
Understanding how the local environment of a single-atom catalyst affects stability and reactivity remains a significant challenge. We present an in-depth study of Cu1, Ag1, Au1, N…
Atomic-scale studies of Fe3O4(001) and TiO2(110) surfaces following immersion in CO2-acidified water
Francesca Mirabella, Jan Balajka1, Jiri Pavelec +5
Difficulties associated with the integration of liquids into a UHV environment make surface-science style studies of mineral dissolution particularly challenging. Recently, we deve…
