The commercial implementation of proton exchange membrane water electrolyzers (PEMWE) is hampered, among other factors, by the high loadings required of the increasingly scarce platinum group metals to effectively catalyze the sluggish oxygen evolution reaction (OER).
My research at the Electrochemical Energy Conversion Team, framed within the DFG SPP 2080 DynaKat project, devotes to:

1) The study of structure-performance relationships of noble metal-based alloys towards the OER: cooperation with Jan-Dierk Grunwaldt and Ulrike Krewer (Karlsruhe Institute of Technology)

2) The use of in situ and in operando coupled electrochemical and surface characterization techniques: SFC-ICP-MS, SFC-DEMS

Other research interests encompass the implementation of earth-abundant catalysts for acidic water eletrolysis, noble metals recycling by advanced dissolution processes and ex-situ electrochemical and physical characterization techniques
