Abstract

Electrochemical decomposition of NO on La0.85Sr0.15MnO3-- Ce0.90Gd0.10O1.95electrodes with and without KNO3 impregnation is investigated. The KNO3 is added as this compound is expected to work as a NOx-storage compound. Measurements are made in the temperature range 300-400 degree C and in three different atmospheres: 1000 ppm NO, 10% O2 and 1000 ppm NO + 10% O2. Electrochemical impedance spectroscopy and cyclic voltammetry are used for electrochemical characterization of the electrodes, and the conversion of NO and O2 is measured on a mass-spectrometer. The results show a significant increase in the NO-conversion, when KNO3 is added to the La0.85Sr0.15MnO3-- Ce0.90Gd0.10O1.95electrodes. ©2010 COPYRIGHT ECS - The Electrochemical Society
