Abstract

Using cone shaped electrodes, the electrochemical reduction of nitric oxide and oxygen has been investigated by cyclic voltammetry on an oxygen overstoichiometric (La_0.85Sr_0.15MnO_3+δ), and an oxygen stoichiometric (La_0.85Sr_0.15CoO_3-δ) 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_0.85Sr_0.15MnO_3+δ compared to the oxygen reduction while the oxygen reduction on La_0.85Sr_0.15CoO_3-δ is faster than the nitric oxide reduction. © 2000 The Electrochemical Society.
