Abstract

A mixed potential sensor based on yttria-stabilized zirconia (YSZ) and a spinel-type oxide sensing electrode (SE) ZnFe2O4 is fabricated and examined for NO2 detection at high temperatures. The devices give a linear correlation between EMF and the logarithm of NO2 concentration from 100 to 1000 ppm in the temperature 450 and 500°C. The mechanism of the sensor has been discussed on the basis of the particle size of sensing electrode-ZnFe2O4.
