This presentation examines heterogeneous catalysis under realistic
conditions by integrating spatially resolved gas-phase and
surface-sensitive diagnostics. Using CO oxidation on palladium as a
model system, the work highlights how catalytic activity is governed
by the interplay between surface chemistry, gas-phase transport, and
dynamic structural changes. Planar laser-induced fluorescence, surface
optical reflectance, X-ray diffraction, and infrared spectroscopy are
combined to identify phases, ignition behavior,
and feedback mechanisms. Studies on polycrystalline samples further
enable orientation-resolved activity mapping, bridging idealized and
technical catalyst systems.
