Enabling deep understanding of Power-to-Ammonia catalysts for renewable fuel production with the help of transient operando photon-in/photon

This LTP is motivated by systematic studies on ammonia synthesis catalysts under the realistic conditions of the Haber-Bosch process, as employed for the production of sustainable renewable ammonia at offshore wind power plants. Over the course of 6 beamtime scheduling periods, electronic and geometric structure of active metals (Fe, Ru) as well as of electronic (K, Cs, Ca, Ba) and structural (Al, Si) promoters will be thoroughly studied at the ID26 beamline under stationary and transient conditions. In the course of the LTP a pixel detector will be installed in the TEXS which, together with sets of high quality Johansson crystals, which will enable X-ray Fluorescence Intensity Ratio Detection (XFIRD). Furthermore, a high pressure operando catalysis cell will be developed. The planned investments will enable spatially- and time-resolved operando tender X-ray HERFD-XANES and XES spectroscopy on working catalysts for chemical energy storage and related processes.
