Research Interests
The expertise of Dr. Tanja Retzer (née Bauer) is the investigation of model and real catalysts by in-situ and operando spectroscopic and microscopic techniques. Depending on the physical state of the sample, IR spectroscopy in diffuse reflectance (DRIFTS), transmission (TIRS) and reflection-absorption mode (IRAS, PM-IRAS) is applied under realistic reaction conditions. Furthermore, model systems and catalysts are analyzed using in situ high resolution AFM. Dr. Tanja Retzer’s group aims at establishing structure-activity relationships that allow for a knowledge-driven design of catalysts. Until 2022, Dr. Tanja Retzer published her research under her maiden name (Tanja Bauer).
