The electrochemical reduction, in an all solid state cell, of NO2 and O2 on LSF (strontium substituted lanthanum ferrite) based electrodes has been studied using the cone-shaped electrode technique. It was shown that the reduction of NO2 occurs much faster on LSF based electrodes than the reduction of O2.
The electrochemical reduction of NO2 on LSF compounds is probably catalyzed by Fe(III) and oxide ion vacancies. The same seems to be true for the electrochemical reduction of O2. The largest difference in current densities for the electrochemical reduction of NO2 and O2 was found for the compound LSF70 (La0.3Sr0.7FeO3−δ).
