Study of the Kinetics of the Interactions of Carbon Monoxide and Oxygen with Al-Zr Surface

摘要

The interaction of CO and O sub 2 with clean Al-Zr (40/60 atomic percent) surfaces have been studied with Auger electron spectroscopy. The initial sticking probability of O sub 2 on Al-Zr was measured to be S/sub 0, O sub 2 / = 0.85. The sticking probabilities of O sub 2 and CO as a function of CO and O sub 2 contamination on a Al-Zr surface have been determined. It is found, that CO adsorption is very sensitive to O sub 2 contamination. The CO contamination is not effective at blocking the surface to subsequent O sub 2 adsorption. (ERA citation 06:008492)
