The main research interest of our group is to obtain a fundamental understanding of catalysts and catalytic reactions. By combining operando spectroscopic characterization of catalysts with reaction kinetics analysis, we aim at establishing structure-performance relations and identifying reaction mechanisms. Understanding the elementary reaction steps at the catalyst surface and identification of the involved intermediates and surface sites is crucial for a rational design and improvement of catalytic materials. Materials of interest include high surface area metal oxides (e.g. ZrO2, CeO2, ZnO, Ga2O3, Al2O3, Co3O4, zeolites, ferrites), sulfides (MoS2) and oxide supported (bi)metallic nanoparticles (e.g. Pd, Au, Ni, Cu, Ag, Pt).
We utilize a range of different state of the art techniques, most of them applied in situ/operando. A main focus is the application of vibrational spectroscopy during reactions both at the solid/gas and solid/liquid interface, including mechanistic studies, isotope labeling and modulation excitation experiments. We complement these studies by examining structure (XRD, EXAFS), electronic properties (XPS, XANES) and available surface sites (FTIR of probe molecules, temperature-programmed methods, chemisorption). NAP-XPS and XAS are carried out within measurements stays at synchrotrons. Several reactor setups are available for performing catalytic tests equipped with GC and MS detection of products.
Our major topics of interest are centered around catalysis for energy and environment with a focus on H2 chemical storage and purification for fuel cell applications, CO2 utilization for production of alcohols, and catalytic conversion of bio-based alcohols, such as bioethanol and glycerol.
Our current research projects involve fundamental research as well as applied research:
- Catalytic CO2 hydrogenation to methanol and higher alcohols (sulfides as sulfur-tolerant catalysts, mixed oxides, alternative synthesis routes)
See also DK CO2Refinery
- Surface chemistry, structure, and reactivity of multi-component spinel nanoparticles
See also SFB Taco
- Polyol hydrogenation over bifunctional catalysts to chemicals and fuel components
- Bimetallic Au-based catalysts for selective alcohol oxidation
- Additive manufacturing of materials with tunable shape and porosity for catalysis applications
- H2 chemical storage: methanol synthesis and steam reforming over Pd-Zn and Pd-Ga intermetallic compounds
- H2 purification: water gas shift, preferential CO oxidation
