Abstract:
Non-faradaic Electrochemical Modification of Catalytic Activity (NEMCA) is a phenomenon by which the rate of a catalytic reaction in an electrochemical cell may be enhanced beyond the rate that could be achieved were the reaction purely electrochemical during the passage of an electric current. Potential applications of this phenomenon are found in catalytic converters, whose catalytic activity might be improved by passing electric currents. Traditional studies of NEMCA are conducted on a relatively thick piece of yttria-stabilized zirconia (YSZ), on which Pt is sputtered as a catalyst electrode. We aim to minimize the amount of YSZ in NEMCA cells to reduce their costs. Thin films of YSZ were deposited on α-alumina disks by dip-coating in YSZ slurry followed by drying and calcination. Pt and Au were sputtered on these YSZ films as the working electrodes and the counter-electrodes, respectively. NEMCA experiments were carried out with stoichiometric propane oxidation as a model reaction at 200-500 Celsius degrees and different imposed cell potentials. As a result, the was found a maximum of 2.69 at a cell voltage of 1.0 V and a reaction temperature of 400 Celsius degrees. The highest of 20,391 was observed at the cell voltage of 0.2 V and a reaction temperature of 300 Celsius degrees. The NEMCA cells are characterized by XRD and SEM.
