Research Group Grunwaldt

Research Group Grunwaldt

Welcome to the Chair in Chemical Technology and Catalysis!

The group's research areas range from preparation, testing to in-depth characterization of catalysts. Applications embrace exhaust gas catalysis, fine chemistry using innovative solvents and the use of renewable resources. Rational design using especially in situ characterization and high-output testing will be combined. Our exhaust gas catalysis activities are part of the exhaust gas centre Karlsruhe.

 

Interest?

Then do not hesitate to contact us or pass by our group!

The new semester start on April 20, 2020 with courses - this time in a digital way.

Do not forget to register early enough in ILIAS, look though the courses of our institute (Link) or write us an Email.

Showcasing research from Professor Grunwaldt and colleagues at the ITCP, IKFT and IMVT at KIT:

Bridging the gap between industry and synchrotron: an operando study at 30 bar over 300 h during Fischer–Tropsch synthesis.

We design new infrastructure for operando high-pressure synchrotron experiments. High structural stability of a Fischer-Tropsch catalyst was found during a long-term study under industrial conditions while producing synthetic fuels.

Oxidation of HMF
Noble metal catalysts for the synthesis of bio-monomers

Novel gold- and silver-based catalysts have been used for the synthesis of potential monomers for sustainable plastics via oxidation of 5-(hydroxymethyl)furfural, an important platform molecule produced from biomass. The catalysts showed distinct selectivities in the oxidation of different functional groups, which made the targeted synthesis of interesting monomers possible.

Graphical Abstract H2O2 Synthesis
Palladium catalyst for hydrogen peroxide synthesis

Research work from ITCP, IKFT, and IMVT was highlighted in Chemical & Engineering News. By looking at a palladium catalyst while it converts hydrogen and oxygen to hydrogen peroxide, researchers have uncovered that α-palladium hydride nanoparticles were responsible for the selective hydrogenation of oxygen to hydrogen peroxide. “This is a very interesting study as it probes the nature of a palladium catalyst under operating conditions and clearly shows the potential role of various palladium hydrides in this challenging reaction,” says Graham J. Hutchings from Cardiff University.
