CO on a Rh/Fe3O4 single-atom catalyst: high-resolution infrared spectroscopy and near-ambient-pressure scanning tunnelling microscopy
Nail El Hocine Barama, Chunlei Wang, Panukorn Sombut +14
Infrared reflection absorption spectroscopy (IRAS) offers a powerful route to bridging the materials and pressure gaps between surface science and powder catalysis. Using a newly d…
Oxygen-Terminated (1x1) Reconstruction of Reduced Magnetite FeO(111)
Florian Kraushofer, Matthias Meier, Zdeněk Jakub +7
The (111) facet of magnetite (FeO) has been studied extensively by experimental and theoretical methods, but controversy remains regarding the structure of its low-energy s…
Real-space investigation of polarons in hematite Fe2O3
Jesus Redondo, Michele Reticcioli, Vit Gabriel +17
In polarizable materials, electronic charge carriers interact with the surrounding ions, leading to quasiparticle behaviour. The resulting polarons play a central role in many mate…
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…
Role of Polarons in Single-Atom Catalysts: Case Study of Me1 [Au1, Pt1, and Rh1] on TiO2(110)
Panukorn Sombut, Lena Puntscher, Marlene Atzmueller +5
The local environment of metal-oxide supported single-atom catalysts plays a decisive role in the surface reactivity and related catalytic properties. The study of such systems is…
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…
Ni modified Fe3O4(001) surface as a simple model system for understanding the Oxygen Evolution Reaction
Francesca Mirabella, Matthias Muellner, Thomas Touzalin +7
Electrochemical water splitting is an environmentally friendly technology to store renewable energy in the form of chemical fuels. Among the earth-abundant first-row transition met…
Self-limited Growth of an Oxyhydroxide Phase at the Fe3O4(001) Surface in Liquid and Ambient Pressure Water
Florian Kraushofer, Francesca Mirabella, Jian Xu +10
Atomic-scale investigations of metal oxide surfaces exposed to aqueous environments are vital to understand degradation phenomena (e.g. dissolution and corrosion) as well as the pe…
Adsorption of CO on the Fe3O4(001) Surface
Jan Hulva, Zdeněk Jakub, Zbynek Novotny +6
The interaction of CO with the Fe3O4(001)-(rt2xrt2)R45° surface was studied using temperature programmed desorption (TPD), scanning tunneling microscopy (STM) and x-ray photoelectr…
Water Agglomerates on Fe3O4(001)
Matthias Meier, Jan Hulva, Zdenek Jakub +7
Determining the structure of water adsorbed on solid surfaces is a notoriously difficult task, and pushes the limits of experimental and theoretical techniques. Here, we follow the…
A Multi-Technique Study of Adsorption on Magnetite
Jiri Pavelec, Jan Hulva, Daniel Halwidl +7
The adsorption of on the (001)-( )R45° surface was studied experimentally using temperature programmed desorption (TPD), electron spe…
