Reaction Kinetic-Induced Changes in the Electrochemically Promoted C2H4 Oxidation on Pt/YSZ

The electrochemical promotion of C2H4 oxidation reaction has been investigated under various feed gas compositions and temperatures over a Pt/Y2O3-stabilized ZrO2 catalyst electrode. It was found that under oxidizing conditions the reaction exhibits electrophobic behavior, i.e. the catalytic rate of CO2 formation increases with anodic potential application, while it shifts to electrophilic behaviour, i.e. the rate increases with cathodic...
