NOx decomposition property of electrochemical cell using synergetic electrodes

Abstract

A new family of electrochemical cell for NOx decomposition in the presence of excess oxygen have been designed and investigated as shown below. (Electro-catalytic electrode (NiO+YSZ)) | Cathode (Pt+YSZ) | Electrolyte (YSZ) | Anode (Pt+YSZ) The small NiO and Ni particles were observed at the interfaces between the NiO/YSZ after cell operation. It might assume that increasing the reaction sites by small NiO and Ni particles generation improved the deNOx performance.
