Sažetak
The catalytic electrochemical reduction of NO with propene was investigated on La0.85Sr0.15MnO3+d/Ce0.9Gd0.1O1.95 symmetrical cells. The electrodes were infiltrated with BaO and Pt. The cells were catalytically active towards the selective catalytic reduction of NOx with propene, but BaO infiltration lowered the NO conversion, probably because of active-site blocking on La0.85Sr0.15MnO3+d. Pt infiltration enhanced the reduction of NOx with propene. When a voltage was applied to the cell with BaO infiltrated electrodes, the NO conversion increased in absence and presence of propene in the feed gas and presence of 10 % O2. The addition of propene into the feed gas did not enhance the conversion of NO when the electrodes were infiltrated with BaO. When platinum was co-infiltrated with BaO, the catalytic activity towards the reduction of NO with propene was enhanced. However, almost no effect was observed when a voltage was applied. Additionally, when the cells were infiltrated with Pt, an electrochemical promotion was observed with respect to CO2 formation.
