Abstract

Copper and silver are important industrially as oxidation catalysts. With the development of atmospheric NOy sensors that utilize CO oxidtion in Au catalytic tubes and with the recent interest in supported Au catalysts which carry out CO oxidation at room temperature, it is important to develop a fundamental understanding of the surface reactions of oxygen on Au. This situation has prompted us to explore the interactions of CO, CO2, H2O, CH3OH, and C2H4 with oxygen adatoms on Au(111) single crystal surfaces. As a simple model reaction, the transiet reaction kintics of CO oxidation with adsorbed oxygen adatoms to form CO2 over Au(111) under clean, UHV conditions and such high oxygen coverages.
