Electrochemical reduction of NO and O2 on oxide based electrodes

Electrochemical reduction of NO and O2 on oxide based electrodes Cyclic voltammetry has been used to investigate the electrocatalytic properties of oxide based electrodes for the reduction of NO and oxygen. Perovskites of compositions LaxSr1-xMnO3+δ, (LSMx), with 0.05 ≤ x ≤ 0.5 and La0.6Sr0.4Fe0.8Mn0.2O3-δ, (LSFM), the spinels Co3O4 and CuCr2O4 and the mixed oxide V2O5 have been selected and investigated in the temperature range 300 – 500 °C. 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. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Ionics Springer Journals

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 LaxSr1-xMnO3+δ, (LSMx), with 0.05 ≤ x ≤ 0.5 and La0.6Sr0.4Fe0.8Mn0.2O3-δ, (LSFM), the spinels Co3O4 and CuCr2O4 and the mixed oxide V2O5 have been selected and investigated in the temperature range 300 – 500 °C. 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.
