Ceramic catalysts inside of reactors made of fused quartz

The group ”Catalysis and Materials Synthesis” combines extensive experience and knowledge of synthesizing optimized materials with measurement techniques for characterizing chemical conversions at ceramic catalysts. Hence structure-property-correlations will be identified and utilized for systematic improvements of the materials properties. Main emphasis is placed on oxygen permeable membranes and oxide catalysts. The coupling of these components in so-called membrane reactors enables a shift of the chemical equilibrium and therefore the enhancement of selectivity and yield via directed dosing of reactants or separation of certain reaction products. Oxygen storage materials (OSM) working in discontinuous processes can also be combined with catalysts and represent an alternative to the continuously working membranes.
