摘要：

Oxygen surface mobility on oxides-supported metals has been studied for many years in our laboratory. The first step of the process is the activation of the oxygen molecule on the metal particle. Measurements of the kinetics of the adsorption-desorption of oxygen on metal surfaces were possible by the way of isotopic exchange studies. The influence of the nature of the metal, of the accessibility of the metal, of the oxide support are reviewed. (C) 2000 Elsevier Science B.V. All rights reserved.
