N2O reduction by CO over Pt electrode in a solid oxide electrolyte cell

摘要: The reduction of nitrous oxide by carbon monoxide in a cell with solid oxygen-conducting electrolyte \( - {\text{CO}} + {\text{N}}_{\text{2}} {\text{O,}}\;{\text{Pt}}\,{\text{|}}\,{\text{0}}{\text{.9ZrO2}} {\text{0}}{\text{.1Y}}_{\text{2}} {\text{O}}_{\text{3}} \,{\text{|}}\,{\text{Pt}} {\text{PrO}}_{\text{2}}\), air – was studied. Experiments were performed the temperature range 410–\(410 670^\circ {\text{C}}\). reaction kinetics under open-circuit conditions and effect current passing through on rate found to depend gaseous composition. In particular: (i) for mixture rich N2O, contrast CO, steady-state multiplicity observed conditions; (ii) slight non-Faradaic enhancement upon cathodic application demonstrated.
