Abstract
The present specification provides a NOx responsive element suitable for directly sensing NOx. The NOx responsive element an oxygen ion conductive layer has a first electrode layer having a nitrogen oxide decomposition catalyst phase composed of perovskite-type oxide, being in contact with the oxygen ion conductive layer, and being exposed to NOx, and a second electrode layer opposing the first electrode layer across the oxygen ion conductive layer. The nitrogen oxide decomposition catalyst phase has a nitrogen oxide adsorption stabilizing surface on its surface exposed to nitrogen oxide.
