Electrochemical Promotion of Propylene Combustion on Ag Catalytic Coatings

Résumé

Catalytic and electrocatalytic measurements have been carried out in a solid oxide cell for propylene combustion using Ag catalytic films deposited on yttria-stabilized zirconia. Competitive adsorption between oxygen and propylene has been observed while catalytic performances can be tailored by current application in a non-Faradaic manner. The predominant impact of current applications is to modify the reactivity of oxygen present on the Ag surface. Positive current applications enhance the propylene conversion by producing more reactive oxygen species. This beneficial effect is more pronounced under lean-burn conditions where the oxygen coverage on Ag is high.
