Abstract

The (La0.8Sr0.2)2FeNiO6- (LSFN) oxide powder with double-perovskite structure was prepared by using polymeric precursor method. The oxide powder and LSFN sensing electrode (LSFN-SE) were characterized by X-ray diffraction (XRD) and environmental scanning electron microscopy (ESEM). The NO sensing property of NOx potentiometric sensor based on yttria-stablized zirconia (YSZ) was investigated from 300 to 550 C in 10 vol.% O2. The results demonstrate that the response of the sensor with LSFN-SE sintered at 1300 C to 600 ppm NO decreases with increasing temperature. The voltage differences of the sensor are good linear to the logarithm of NO concentrations. The NO gas adsorption-desorption behavior of the LSFN was examined. The result of NO-TPD indicates that desorption peak is not observed above 300 C, which may be one of the reasons for the low sensitivity of NO for the LSFN.
