NO[sub x] Sensing Characteristics of Mixed-Potential-Type Zirconia Sensor Using NiO Sensing Electrode at High Temperatures

Abstract

A stabilized-zirconia-based NO x sensor attached with oxide sensing-electrode (SE) was tested for the detection of NO x at temperatures higher than 800°C for car-emission control applications. Among various oxide SEs tested, NiO was found to give the highest sensitivity to NO 2 even at high temperatures. It was found that the sensor using NiO-SE showed quicker recovery in the presence of water vapor, compared with that in the dry sample gas. Electromotive force values of 57 and 75 mV were observed, respectively, under dry and wet (5 vol % water vapor) conditions with 400 ppm NO 2 at 850°C.
