Abstract

The charge transfer reactions between a Pt catalyst and an yttria-stabilized zirconia support have been studied electrochemically during CO oxidation. The activation energies for the charge transfer reactions and the effect of operating conditions on the adsorbate composition have been estimated from a combination of electrochemical and reaction-rate measurements obtained over a range of gas phase compositions at temperatures typical of automotive exhaust. The results are interpreted mechanistically on the basis of a model involving both molecularly and dissociatively adsorbed oxygen.
