Space- and Time-Resolved Investigation of the Gas Phase and the Active Surface/Bulk (C04)

• Subject Area: Technical Chemistry
• Term: since 2021
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 426888090

The project investigates structural and gas phase concentration gradients that develop in the channels and walls of monolithic catalysts during operation. In-situ and operando methods are developed and applied to simultaneously investigate spatial and temporal changes in the gas phase and in the catalyst. These include non-invasive laser and X-ray methods combined in a specially developed in situ cell to study the gas phase by planar laser-induced fluorescence and the catalyst by X-ray absorption spectroscopy. Detailed reaction mechanisms are used to model the reactor behavior and to develop strategies for re-/activation of the catalyst focusing first on NH3 and VOC oxidation.
