Turek group


The working group develops methods for the design of chemical and electrochemical reactors in which porous catalysts or electrocatalysts are used. On the micro- and mesoscale, issues relating to the design of pore systems are addressed in order to improve the transport and distribution of liquid and gaseous reactants with regard to the best possible utilization of the porous reaction system. In addition to a comprehensive characterization of the pore systems and the measurement of the effectiveness of the catalysts and electrocatalysts, mathematical models for the coupling of transport and reaction on the pore scale are also required. On the macroscale, the geometric design of catalysts and electrodes as well as the chemical or electrochemical reaction apparatus is investigated in order to achieve the highest possible efficiency of external mass and heat transport. Dynamic processes are also becoming increasingly important in this context, bringing with them new challenges with regard to the description of reaction kinetics and reactor modeling.
