Laterally Condensed Catalysts (LCCs) — few nm thin, film-like 2D catalysts — are ideally suited for advanced spectroscopy at synchrotron facilities such as BESSY II and EMIL. Their well-defined geometry and nanometer-scale thickness enable precise XPS and NEXAFS studies, including depth profiling across catalyst layers. Moreover, LCCs are compatible with in situ and operando measurements, making it possible to follow thermal catalysis (e.g., acetylene hydrogenation) as well as pretreatment steps such as oxidation and reduction. This unique combination provides unparalleled insight into catalytic structure and function under realistic conditions.
