Rupprechter Research Group - Model Catalysis and Applied Catalysis

A. Overview

My group's strategy is to study catalytic surface reactions on heterogeneous catalysts via a four-fold approach, employing

1. Model Catalysis and Surface Science

2. Atomically-precise Cluster Catalysis

3. Applied industrial-grade Catalysis

4. Microkinetic Modeling and Simulation

For the first three, the focus is on examining active functioning catalysts under operando conditions by surface spectroscopy (PM-IRAS, FTIR, ATR, DRIFTS, SFG, NAP-XPS, XANES, EXAFS) and surface microscopy (PEEM, FEM, FIM, SPEM), preferentially at realistic temperature and (near) atmospheric pressure, with simultaneous GC or MS analysis of catalytic performance. In many cases the interpretation and verification of the obtained experimental spectra/images/patterns relies on theoretical support, e.g., by calculating structures, adsorption and activation energies for single crystal surfaces, nanoparticles and clusters, complemented by microkinetic reaction modeling.

This four-fold approach yields a more “holistic” view of the catalytically relevant atomic and electronic surface structure of catalysts, as well as of molecular details that steer reaction activity and, even more important, reaction selectivity. Comparing single crystals with nanoparticle or cluster model catalysts elucidates the materials gap, and comparing UHV to ambient pressure studies reveals the pressure gap. In particular, synergisms between studies on model and technological catalysts often provide access to atomistic details. Novel approaches to imaging surface reactions (kinetics by imaging) on model catalysts (surface structure and particle size libraries) by PEEM/FEM/FIM/SPEM have turned out particularly powerful. Most studies are performed in lock-step with intense theory collaborators.

B. Research Directions

1. Model Catalysis and Surface Science

(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.

2. Atomically-precise Cluster Catalysis

(previous FWF funded projects: DK+ Solids4Fun, ComCat)

Metal clusters are synthesized with precise atomic number (< 100 atoms, e.g. Au25, Au38 or Au144) and, when deposited on a support (CeO2, TiO2, SiO2, Al2O3), comprise truly monodisperse catalysts. The catalytic properties of clusters are often unique, due to their quantized electronic structure and specific atomic structure, and may differ strongly from those of larger nanoparticles (> 100 atoms). The possibility of creating atomically precise and even doped nanoclusters should finally lead to improved catalysts and a better understanding of nanocatalysis. Operando XAS studies are performed at various synchrotron sources.

3. Applied industrial-grade Catalysts

(previous FWF funded projects: 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.

4. Microkinetic Modeling and Simulation

(FWF funded projects: SFB TACO,OEAD)

The developments in operando methodology enable to relate the catalyst state to its performance under reactive conditions. However, in many cases the interpretation and verification of the obtained experimental spectra/images/patterns relies on theoretical support, e.g. by calculating structures, adsorption and activation energies for single crystal surfaces, nanoparticles and clusters, complemented by micro-kinetic reaction modelling. Clearly, if calculations are performed for realistic gas pressures (coverage) and temperatures, they are even more relevant for operando studies.
