Abstract

Cyclic voltammetry has been used to investigate the electrocatalytic properties of oxide based electrodes for the reduction of NO and oxygen. Perovskites of compositions La_xSr_1-xMnO_3+δ, (LSMx), with 0.05 ≤ x ≤ 0.5 and La_0.6Sr_0.4Fe_0.8Mn_0.20_3-δ, (LSFM), the spinels Co₃0₄ and CuCr₂0₄ and the mixed oxide V₂0₅ have been selected and investigated in the temperature range 300 - 500 ºC. The materials show good catalytic properties against both NO oxidation and NO reduction. The catalytic activity as well as the selectivity is dependent both on the redox behavior of the compound and on the oxygen defect concentration.
