Abstract

A computer model was developed to take into account all the phenomena that can occur in <superscript>18</superscript>O/<superscript>16</superscript>O isotopic exchange over Pt/CeZrO<subscript>x</subscript> materials: adsorption/desorption on the metal, surface and bulk O diffusion. Discriminating each step of the exchange process is no longer necessary: kinetic parameters and O diffusivity can be calculated in a single experiment. [ABSTRACT FROM AUTHOR]
