The work group "Emission Reduction" deals with the heterogeneous catalytic conversion of air pollutants and harmful exhaust gas components from combustion processes.
A sustainable high air quality is controlled by legal regulations for the reduction of the emission of pollutants. In Germany, for example, these emissions are regulated by the Federal Immission Control Act (Bundesimmissionsschutzgesetz, BImSchG). Increasingly strict regulations require more efficient filter and catalyst systems. Consequently the central research interests of the work group Emission Reduction are the development of new and the optimization of existing catalytic systems for the avoidance of air pollutants. Research emphases are the selective catalytic reduction (SCR) of nitric oxides using ammonia or ethanol and the photocatalytic NOx-reduction. Besides the preparation of optimized catalysts for established and new applications as well as the testing of the catalytic behavior of different catalysts (SCR-catalysts, diesel oxidation catalysts and catalytic coated diesel particle filters), the understanding of the mechanisms for their aging and deactivation are in the focus of research.
