Mixed Potential Type Sensor Using Stabilized Zirconia and La_0.75Sr_0.25Cr_0.5Mn_0.5O₃ Sensing Electrode for NO₂ Detection

Abstract:

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 La_0.75Sr_0.25Cr_0.5Mn_0.5O₃, shows extreme sensitivity to NO₂. The EMF varies linearly as a function of the concentration of NO₂ (0~ 463 ppm) at 773K.
