The oxidation of propylene on porous polycrystalline Ag films supported on yttria-stabilized zirconia was studied in a CSTR at temperatures between 290 and 400/sup 0/C and atmospheric total pressure. Steady state kinetic measurements were combined with simultaneous in situ monitoring of the chemical potential of oxygen adsorbed on the silver catalyst, using the technique of solid electrolyte potentiometry (SEP). The kinetic and potentiometric results are consistent with a Langmuir-Hinshelwood reaction model with two types of chemisorbed oxygen. The reaction network kinetics are studied thoroughly and compared with those obtained during oxidation of propylene oxide, ethylene, and ethylene oxide on the same catalytic surface.
