Abstract

This thesis described the growth and structure of the Ag/Pt(111) surface alloy and its interaction with oxygen. The alloy was investigated using spot profile analyses low energy electron diffraction (SPA-LEE), low energy electron microscopy (LEEM), and thermal desorption spectroscopy (TDS). This combination allows a detailed characterization of the structure and morphology, at sub-monolayer and higher coverage of Ag. Complex processes of alloying, dealloying, surface phase transitions, segregation, and the formation of a dislocation network at the buried interface are observed, as well as the affinity to the dissociative absorption of oxygen, a vital step in catalytic oxidation reactions.
