Title: Perovskites as cathodes for nitric oxide reduction

Abstract

Using cone shaped electrodes, the electrochemical reduction of nitric oxide and oxygen has been investigated by cyclic voltammetry on an oxygen overstoichiometric (La{sub 0.85}Sr{sub 0.15}MnO{sub 3+{delta}}), and an oxygen stoichiometric (La{sub 0.85}Sr{sub 0.15}CoO{sub 3{minus}{delta}}) perovskite over the temperature range 300--500 C. An oxygen ion-conducting 10% gadolinium-doped cerium oxide is used as electrolyte. It is shown that the reduction of nitric oxide proceeds rapidly on La{sub 0.85}Sr{sub 0.15}MnO{sub 3+{delta}} compared to the oxygen reduction while the oxygen reduction on La{sub 0.85}Sr{sub 0.15}CoO{sub 3{minus}{delta}} is faster than the nitric oxide reduction.
