News and interesting facts about the Center for Emission Control Karlsruhe

Future of Emission Control Conference (21.-23.07.2024, Karlsruhe, Germany): our satellite conference to the ICC2024

Emission control is recognized as a technology that is traditionally very important for clean air and will enable progress in other areas - most notably the energy transition, which is considered one of the most pressing issues of our time. In the 2-day conference we aim to bring together the international community in the field of emission control and to present and discuss new challenges, concepts and solutions in the scientific field. 


New paper on the importance of operando spectroscopy for catalyst development

Bidyut Bikash Sarma and Jan-Dierk Grunwaldt show in their new publication in CHIMIA that for understanding the catalyst system under true reaction conditions, operando spectroscopy is the key to unravel small changes, which can ultimately lead to a significant difference in catalytic activity and selectivity. (Sarma, Bidyut Bikash, and Jan-Dierk Grunwaldt. "Operando Spectroscopy to Understand Dynamic Structural Changes of Solid Catalysts." Chimia 78.5 (2024): 288-296.)


New review paper on the exhaust gas after-treatment of lean-burn natural gas engines

Several colleagues contributed to the new review article on the main challenges for the emission control of lean-burn engines, which was recently published in Appl. Catal. B. (Lott, Patrick, et al. "Exhaust gas after-treatment of lean-burn natural gas engines–from fundamentals to application." Applied Catalysis B: Environmental (2023): 123241.)


New review paper on the Design and Operando Monitoring of Single-Atom Catalysts

The potential of operando X-ray techniques for following the structure and fate of the active species in single-atom catalysts is highlighted in the new review published by Bidyut Bikash Sarma et al. in Chemical Reviews. (Sarma, Bidyut Bikash, et al. "Design of single-atom catalysts and tracking their fate using operando and advanced X-ray spectroscopic tools." Chemical Reviews 123.1 (2022): 379-444.)


New paper on the effect of NM concentration on ceria surface for in situ catalyst activation

In their recent paper in ASC Catalysis, Maurer et al. show that Pt diffusion barriers for cluster formation decrease with increasing the surface noble metal concentration SNMC on ceria, promoting more facile agglomeration of highly active metallic Pt particles. (Maurer, Florian, et al. "Surface noble metal concentration on ceria as a key descriptor for efficient catalytic CO oxidation." ACS Catalysis 12.4 (2022): 2473-2486.)

The 27th North American Catalysis Society Meeting in May 2022

We will be at the 27th North American Catalysis Society Meeting in New York with a talk given by Kevin Keller on “Catalytic Total Oxidation of Methane – Towards a Better Understanding of the Water Inhibition Effect and the Influence of the Support Material”. We are looking forward to inspiring discussions. See you there!

Save the new date: MODEGAT VII postponed until 2022

The next international symposium on Modeling of Exhaust-Gas After-Treatment (MODEGAT) will be held in 2022. The organizers believe that the interactive and collaborative spirit of MODEGAT is best created through face-to-face contact and have therefore decided against a virtual format. MODEGAT VII will take place September 11-13, 2022, in Bad Herrenalb/Karlsruhe, Germany. For updates regarding a call for abstracts, registration, and more visit the conference website! January 2021.


Excellence Award of the VAA Foundation for Patrick Lott

Deutschmann group Senior Scientist Dr. Patrick Lott received the Excellence Award of the VAA Foundation during a small, festive ceremony in Cologne. The prize, which is endowed with € 5,000, is awarded once a year in recognition of outstanding dissertations with industrial application relevance. December 2020.


How catalysts can work more efficiently

The DFG funds a new Collaborative Research Centre (CRC 1441) “Tracking the Active Site in Heterogeneous Catalysis for Emission Control” (TrackAct) for the understanding of catalytic processes. The vision of TrackAct is to design noble metal catalysts with atomic precision and to monitor and control the active site in the reactor and the technical application. December 2020.


Scholarship for Daria Gashnikova

Daria Gashnikova has received a Kékulé scholarship for her doctoral thesis. Congratulations!

  • Applied Chemistry and Chemische Technik III, coordinated by Olaf Deutschmann
  • “Catalysis for sustainable chemicals and energies" and "Characterization in Materials Science and Catalysis",  coordinated by Jan-Dierk Grunwaldt
  • “Grundlagen der katalytischen Abgasnachbehandlung bei Verbrennungsmotoren“ , coordinated by Egbert Lox (Umicore), Jan-Dierk Grunwaldt and Olaf Deutschmann

Project "AdBlue Deposits"

The FVV project „AdBlue Deposits“ (01/2017 - 04/2019) funded by the BMWi through the AiF investigated the interaction between injected AdBlue solution and the exhaust tract. A particular focus was on the resulting film formation and the compounds precipitating from the liquid film. In addition to experimental considerations, new models for urea decomposition, spray/wall interactions and heat transfer processes were investigated.

New catalyst concept developed

The study Tuning the Structure of Platinum Particles on Ceria In Situ for Enhancing the Catalytic Performance of Exhaust Gas Catalysts by A. M. Gänzler, M. Casapu et al., published in Angewandte Chemie, presents a new catalyst concept. In the study, the size and state of the precious metal nanoparticles on the catalyst surface can be adjusted to react to external influences such as the exhaust gas composition in order to achieve an optimal result. In the future, exhaust gases could be efficiently treated and precious metals could be saved even during cold starts of engines and in city traffic. Press release KIT 151/2017. September 2017.
