Catalysis on platinum surfaces probed using synchrotron-based core-level spectroscopies
Abstract/Contents
- Abstract
- Probing chemical reactions on solid surfaces in situ remains a major challenge in heterogeneous catalysis, because most methods of surface characterization require ultrahigh vacuum (UHV) conditions. In addition, the effects of morphology, particle size, and chemical composition are frequently difficult to disentangle due to sample heterogeneity. This work addresses these limitations by applying synchrotron-based core-level spectroscopies to well-defined systems based on single crystals. With a view to developing improved electrocatalysts for the oxygen reduction reaction (ORR) in fuel cells, the behavior of oxygenated species on the Pt(111) and Pt/Rh(111) surfaces was examined in situ under both electrochemical and ambient-pressure conditions using high-energy-resolution fluorescence-detection x-ray absorption spectroscopy (HERFD XAS) and ambient-pressure x-ray photoelectron spectroscopy (APXPS), respectively.
