In the etzoldlab

In the etzoldlab the challenges arising with the needed global energy change and future sustainable feedstock supply for chemical industry are the major research guideline. From the perspective of applied chemistry, a multidisciplinary approach is employed to provide scientific solutions for these challenges, especially for the complex interplay of catalytic materials within a full process or device. In the scientific approach, generic experiments play a dominant role. They allow controlling process conditions from highly idealized towards technically realistic and are combined with diagnostics providing in-situ information. Chemical reaction engineering simulations complement the experiments, giving especially insights into complex mass transfer phenomena and, therefore making a more holistic picture possible. As a future sustainable energy and chemical industry will need a concerted interaction of electrochemical and classical heterogeneous catalyzed processes both are studied. Based on this strategy, the research of the etzoldlab can be divided in three strongly interacting sub-groups: Advanced Catalytic Materials – Electrochemical Energy Conversion Processes – Heterogeneous Catalysis and Processes. More details on the research of these subgroups can be found in the sections below.
