Abstract:
The effects of electrochemical promotion of catalysis (EPOC) or non-faradaic
electrochemical modification of catalytic activity (NEMCA) of isolated Pt catalyst on Y2O3-
stabilized-ZrO2 (YSZ) disks, an O2- conductor, were studied with the catalytic reaction of
propane oxidation, which was chosen to model the combustion of residual hydrocarbons in
catalytic converters. In electrochemical promotion, the catalyst was electrochemically
promoted by applying electric current or potential between two terminal Au electrodes
supported on solid electrolyte (wireless configuration). Catalytic performances were studied
under stoichiometric amount of oxygen at atmospheric pressure, in the range of temperature
of 200400 °C by application of electrical potential of 030 V. The induced rate increase (Δr)
exceeded the corresponding electrochemically controlled rate I/nF of O2- transfer through the
solid electrolyte, resulting in the faradaic efficiency Ʌ = Δr/(I/nF) up to 4.45 × 103 achieved at
300 °C with cell voltage of 5 V for a sputtered Pt loading of 0.1105 mg Pt/m2. Sputtered
electrochemical catalysts presented significantly larger catalytic activity, which may be
related with formation the of PtOx species during electrochemical promotion.
