Water adsorption on a model silicate surface: wollastonite (100)
Luca Lezuo, Andrea Conti, Alexander Hoheneder +7
Water adsorption on silicate surfaces is a critical yet poorly understood process relevant to, e.g., mineral weathering and cement hydration. This study investigates the structure…
Photoexcited Hole States at the SrTiO3(001) Surface Imaged with Noncontact AFM
Igor Sokolovic, Florian Ellinger, Aji Alexander +8
The behaviour of excess charges in ionic lattices, such as the formation of polarons and charge trapping at defect sites, influences the physical and chemical properties of materia…
The Unreconstructed α-AlO(0001) Surface is Inhomogeneous and Rough
Johanna I. Hütner-Reisch, Andrea Conti, David Kugler +4
Alumina (AlO) is a key material for thin-film growth and heterogeneous catalysis, where the atomic surface structure critically impacts performance. Using noncontact at…
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…
Hydrogen Activation via Dihydride Formation on a Rh1/Fe3O4(001) Single-Atom Catalyst
Chunlei Wang, Panukorn Sombut, Lena Puntscher +10
Hydrogen activation is a key elementary step in catalytic hydrogenation. In heterogeneous catalysis, it usually proceeds through dissociative adsorption on metal nanoparticles foll…
Structural Optimization in Tensor LEED Using a Parameter Tree and -Factor Gradients
Alexander M. Imre, Paul Haidegger, Florian Kraushofer +10
Quantitative low-energy electron diffraction [LEED ] is a powerful method for surface-structure determination, based on a direct comparison of experimentally observed …
