Dynamics of Dissociative Chemisorption: Methane on Tungsten Single Crystal Surfaces
Abstract
dc:descriptionChemisorption of simple molecular gases on clean metal surfaces is usually rapid, with vanishingly small activation energies and large sticking coefficients. However, for more complicated molecules, such as saturated hydrocarbons, chemisorption is often a slow process which involves thermal excitation over relatively high barriers. We have studied one such system: the dissociation of methane on clean tungsten single crystal surfaces. The purpose of this study is to explore the nature of the elementary excitations which bring about dissociation and subsequent adsorption. Our effort has been concentrated upon studying the effect of thermal excitations of the gas as well as the importance of the crystal structure of the metal surface.
