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…
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…
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…
A study of Pt, Rh, Ni and Ir dispersion on anatase TiO2(101) and the role of water
Lena Puntscher, Kevin Daninger, Michael Schmid +2
Understanding how metal atoms are stabilized on metal oxide supports is important for predicting the stability of single-atom catalysts. In this study, we use scanning tunnelling m…
A Multi-Technique Study of C2H4 Adsorption on Fe3O4(001)
Lena Puntscher, Panukorn Sombut, Chunlei Wang +10
The adsorption/desorption of ethene (C2H4), also commonly known as ethylene, on Fe3O4(001) was studied under ultrahigh vacuum conditions using temperature programmed desorption (TP…
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…
