Mixed Potential Type Sensor Using Stabilized Zirconia and La0.75Sr0.25Cr0.5Mn0.5O3 Sensing Electrode for NO2 Detection
Electrochemical sensors based on tubular yttria-stabilized zerconia (YSZ) with the perovskite-type oxide as a sensing-electrode (SE), which is prepared by sol-gel method, were fabricated and examined for NO2 detection in the temperature range 673~973K. The results show that La0.75Sr0.25Cr0.5Mn0.5O3, shows extreme sensitivity to NO2. The EMF varies linearly as a function of the concentration of NO2 (0~ 463 ppm) at 773K.
