In situ Studies of Adsorbate Induced Surface Dynamics in Model Catalyst Systems

The surfaces of noble metal model catalyst systems were studied in the presence of reactive gases. The restructuring of the metal surface layers in response to the background gases and adsorbates was observed using Ambient Pressure STM and XPS. The ambient pressure surface behavior will be presented for the reaction of ethylene and hydrogen on Pt single crystals and the behavior of bimetallic nanoparticles in oxidizing and reducing environments to show how the atomic level surface properties change under reactive conditions.
