Model Catalysis and Surface Science

Research Directions

(current FWF funded projects: SFB TACO, Single Atom Catalysis, Spatial-temporal phenomena on surface structure libraries)

Surface Spectroscopy

Model catalysts such as single crystals, thin films, polycrystalline foil and supported nanoparticles are prepared in UHV and characterized by XPS, (PM-)IRAS, SFG, STM, LEED, AES, LEIS, TPD, etc. After transfer into UHV-compatible high pressure cells (“Rupprechter design”), operando studies of the catalytically active surfaces are performed by polarization-modulation infrared reflection absorption spectroscopy (PM-IRAS) and sum frequency generation (SFG) laser spectroscopy. Near atmospheric pressure X-ray photoelectron spectroscopy (NAP-XPS) and X-ray absorption (XAS) are performed at various synchrotron sources.

Surface Microscopy

To image ("see") ongoing surface reactions (reaction fronts and oscillatory behavior) by in situ spatially-resolved surface microscopy, photoemission electron microscopy (PEEM) is applied to polycrystalline foil, thin films and oxide supported (micrometre) particles, with averaging (global) catalytic data recorded by MS. Scanning Photoelectron Microscopy (SPEM) allows local surface analysis on a sub-μm-scale. Field emission/ion microscopy (FEM/FIM) is utilized to image reactions on curved crystals and nanotips, modeling individual nanoparticles of a catalyst, enabling single particle catalysis.    

Instrumentation

SFG: UHV chamber (LEED, AES, TPD) with high pressure cell (SFG, MS)
