Abstract
The role of bulk carbon in determining the high temperature stability of oxygen on carbon-free Ni surfaces has been investigated. Oxygen adsorbed on a room temperature carbon-free Ni surface reacts, upon subsequent heating, with bulk carbon to form a CO desorption product. This reaction has been studied over a wide range of oxygen exposures using Auger electron spectroscopy (AES) and temperature programmed desorption (TPD). TPD data for oxygen-covered Ni surfaces reveal three principal CO desorption states.
