Center for Emission Control Karlsruhe                     

The Center for Emission Control Karlsruhe is one of the largest research organizations in Germany exclusively dedicated to the catalytic removal of pollutants. Founded in 2010 as an interdisciplinary organization at the Karlsruhe Institute of Technology, Germany, the center brings together the catalysis research groups from the Institute for Chemical Technology and Polymer Chemistry with complementary expertise ranging from catalyst preparation and testing to in-depth characterization, modeling and simulation of chemical reactions and transport phenomena. Herewith, all length-scales relevant for emission control are considered, starting from an atomic-level understanding to design of full-scale realistic catalysts and reactors.


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. June 2024.
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. April 2023.
Hunting the active site in a catalyst

How do catalysts work and what do they look like during the reaction? These are the key questions for the development of efficient catalytic processes, the understanding of which is the ultimate goal of the interdisciplinary Collaborative Research Center (CRC) TrackAct. The CRC is presented in a video. March 2024.
How are catalysts studied comprehensively?

Numerous members of the Center for Emission Control Karlsruhe are engaged in the Collaborative Research Center TrackAct. Get to know the different departments in a video! Herein, scientists of different departments present their work - from catalysts in the microcosm to hand-sized, applied catalysts. March 2024.

Tail pipe emission reduction
Tailpipe emission reduction of hybrid electric vehicles by periodic operation

In collaboration with the Waseda University in Tokyo and Japanese automobile manufacturers, a new process has been developed to increase the efficiency of the three-way catalytic converter in a hybrid-electric vehicle at low exhaust temperatures. Inhibition of the catalytic converter by blocking the active sites at low temperatures can be prevented by periodic lean-rich switches of the exhaust gas. The work contributes to a better understanding of periodic processes in exhaust gas catalysis and has recently been published in Appl. Catal. B: Environ. January 2024.
New review paper on the exhaust gas after-treatment of lean-burn natural gas engines

In a new review article, several colleagues summarized the main challenges for the efficiently controlling emissions from lean-burn natural gas engines. The article was recently published in Appl.

We are looking forward to inspiring discussions. See you there! March 2022.
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. February 2022.
