Research Directions

(ongoing and previous FWF funded projects: COE MECS, opens an external URL in a new window, SFB TACO, SFB FOXSI, DK+ Solids4Fun, ComCat, DryRef)

Studies of technological (industrial grade “powder”) catalysts in (automated) continuous-flow fixed-bed quartz reactors under atmospheric pressure. Spectroscopic studies are preferentially performed under operando conditions, by Fourier transform infrared spectroscopy (FTIR), diffuse reflectance infrared fourier transform spectroscopy (DRIFTS), X-ray absorption spectroscopy (XAS), near atmospheric pressure X-ray photoelectron spectroscopy (NAP-XPS), and X-ray diffraction (XRD). Most of the operando studies are performed at synchrotron sources.

Instrumentation

FTIR, DRIFTS, ATR, chemisorption, BET, TPD/O/R, UV-Vis, PL, various (automated) flow reactors (GC, MS)
