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.

Spatially-resolved insights into local activity and structure of Ni-based CO2 methanation catalysts in fixed-bed reactors

The catalytic hydrogenation of CO2 is a promising way to store large amounts of renewable energy while reducing CO2 emissions (P2X concept). Marc-André Serrer (IKFT), Matthias Stehle (ITCP) and further colleagues at IKFT, ITCP and IAM-AWP uncovered the reaction progress along a conventional Ni-based and an advanced Ni-Fe-based catalyst during CO2 methanation in a fixed-bed reactor. By using a dedicated new setup, they were able to reveal changes in activity, selectivity, and temperature along the catalyst bed. Complementary spatially resolved structural investigations by X-ray absorption spectroscopy showed that the oxidation state of Fe is strongly influenced by the increasing amount of water towards the end of the catalyst bed. Furthermore, infrared spectroscopy unraveled that Fe species promote the higher activity of the bimetallic catalyst by protecting active Ni0 centers from strongly adsorbed CO. Hence, this example underlines not only the importance to consider gradients in chemical reactors but that they even can be exploited for better understanding.

Collaborative Research Centre TrackAct started at KIT

Just now the Collaborative Research Centre 1441 TrackAct (Tracking the Active Site in Heterogeneous Catalysis for Emission Control) at Karlsruhe Institute of Technology (KIT) has started. Catalysis is at the core of the initiative that is conducted together with partners in Munich and the synchrotron radiation source in Hamburg. Within this program, we thus seek for PhD candidates in various fields from Chemistry, Chemical Engineering, Material Sciences to Physics, for more information see here: www.trackact.kit.edu/159.php

Chemical gradients in automotive Cu-SSZ-13 catalysts for NOx removal revealed by operando X-ray spectrotomography

Gradients in the copper oxidation state and coordination environment of Cu-SSZ-13 catalyst were observed using XANES tomography. For this purpose, a newly developed setup was used that allows XANES tomography to be performed under realistic (operando) conditions. The interplay of adsorption-desorption processes and mass transfer effects was analysed with micrometre resolution in 3D.

Tracking the formation, fate and consequence for catalytic activity of Pt single sites on ceria

The location of platinum single sites on ceria and the variation of the active state were investigated in an operando approach while combining different methods like in situ infrared spectroscopy, operando high-energy-resolution fluorescence detected X-ray absorption spectroscopy, catalytic CO oxidation and density functional theory calculations.

Virutal Workshop with Prof. Dr. Soldatov (SFedU, Rostov-on-Don, RU)

On October 7th, the groups of Prof. Dr. Grunwaldt (KIT, Karlsruhe, DE) and Prof. Dr. Soldatov (SFedU, Rostov-on-Don, RU) held a joint virtual workshop on Hard X-ray Spectroscopy and Advanced Data Analysis for Catalysis. The workshop brought together over 50 scholars from Germany – Karlsruhe Institute of Technology, and Russia – The Smart Materials Research Institute at the Southern Federal University. The talks were devoted to the infrastructure and experimental research highlights from KIT as well as the advances of SFedU in the areas of machine learning, big data analysis and prediction of X-ray absorption spectra for catalytically active materials.

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.

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.
