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.




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




Open PhD and Postdoc-Positions

Do not hesitate to write us if you are interested in catalysis, biomass conversion, spectroscopy, or solid state chemistry.

Catalysis Science & Technology - Cover Article

Pt-based diesel oxidation catalysts were exposed to rapid transient temperature conditions based on a realistic driving cycle. A microreactor setup was used for rapid heating/cooling coupled to operando X-ray absorption spectroscopy and on-line mass spectrometry. Major differences in catalyst structure and performance were observed under transient conditions compared to model studies.

CAT-ACT opening workshop

On 20. and 21. September 2017 a two day workshop dedicated to the inauguration of KIT´s new beamline for catalysis and actinide research (CAT-ACT) will take place in the ANKA

seminar room (KIT Campus North, building 348, 1st floor, west entrance). CAT-ACT is jointly operated by the KIT institutes INE (for radionuclide science) and IKFT/ITCP (for catalysis research).

The workshop will highlight research activities and access possibilities at CAT-ACT and particularly cover the following topics: Introduction to CAT-ACT and lab infrastructure, overview and highlight talks on XAS in Catalysis and Actinide research, involved KIT/HGF research programs, KIT in-house research activities and projects with cooperation partners, and future research perspectives.

Preceding the workshop a two days training course providing an overview on XAFS methods, theory and data analysis will be offered. Registration deadline is 1 September 2017. Further information: here

3D X-ray tomography

Cutting-edge synchrotron X-ray tomography was applied to image catalysts at work. The structure of a core@shell catalyst for direct synthesis of dimethyl ether (DME) was detailed in 3D, in situ and simultaneously by X-ray diffraction, fluorescence and absorption tomography; revealing important information about catalyst structure and function which is unavailable using conventional methods.

Priority Program SPP2080

The DFG establishes the priority program “Catalysts and Reactors under Dynamic Operation Conditions for Energy Storage and Conversion” (SPP 2080). Coordinator of the SPP 2080 is Prof. Dr. Jan-Dierk Grunwaldt. Project outlines can still be submitted until the 10th of September 2017, the deadline for full proposals is the 8th of January 2018.

6 years at KIT now

The AK Grunwaldt has started on February 1, 2010, in Karlsruhe!

Autumn 2015: The optics of "CAT-ACT" at ANKA is successully taken into operation. At the same time the first in situ XAS spectra are collected at the PETRA III extension in Hamburg on catalysts!

March 2014: Prof. Jan-Dierk Grunwaldt is member of the "Kommission der Deutschen Gesellschaft für Katalyse (GeCatS)" and elected for the "Kommittee für Synchrotronstrahlung" in Germany.

Februar 2014: Dr. Ying Zhou is granted a "Humboldt-Stipendium".

December 2013: The Wiggler for CAT-ACT at ANKA arrives. FMB-Oxford presents the beamline design for CAT-ACT and green light is given for the optical design.

June 2013: The BMBF supports the proposals "ZeitKatMat" (Collaboration with Prof. Ronald Frahm and Prof. Andreas Jentys) and "Nanoskop" (Collaboration with Prof. C.G. Schroer, TU Dresden) for exploiting the newest experimental methods at the synchrotron in catalysis.
