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…
Multi-Technique Characterization of Rhodium Gem-Dicarbonyls on TiO(110)
Moritz Eder, Faith J. Lewis, Johanna I. Hütner +12
Gem-dicarbonyls of transition metals supported on metal (oxide) surfaces are common intermediates in heterogeneous catalysis. While infrared (IR) spectroscopy is a standard tool fo…
Digging its own Site: Linear Coordination Stabilizes a Pt1/Fe2O3 Single-Atom Catalyst
Ali Rafsanjani-Abbasi, Florian Buchner, Faith J. Lewis +15
Determining the local coordination of the active site is a pre-requisite for the reliable modeling of single-atom catalysts (SACs). Obtaining such information is difficult on powde…
Quantitative measurement of cooperative binding in partially dissociated water dimers at the hematite R-cut surface
Paul T. P. Ryan, Panukorn Sombut, Ali Rafsanjani Abbasi +7
Water-solid interfaces pervade the natural environment and modern technology. On some surfaces, water-water interactions induce the formation of partially dissociated interfacial l…
A Multi-Technique Study of C2H4 Adsorption on a Model Single-Atom Rh1 Catalyst
Chunlei Wang, Panukorn Sombut, Lena Puntscher +9
Single-atom catalysts are potentially ideal model systems to investigate structure-function relationships in catalysis, if the active sites can be uniquely determined. In this work…
