Abstract

Electrochemical NO_x sensors based on coupling yttria stabilized zirconia (YSZ), an oxygen-ion conductor, with different semiconducting oxides as auxiliary phase were studied. Nanosized LaFeO₃ perovskite-type oxide, a p-type semiconductor, and n-type WO₃ were used as auxiliary phases because of their NO₂ sensing properties in resistive-type devices. LaFeO₃ or WO₃ thick films were deposited using a screen printing oil on one side of the solid-electrolyte pellets. The sensors were fully exposed to the same atmosphere. Electromotive force (EMF), polarization curves, amperometric and electrochemical impedance spectroscopy (EIS) measurements, were performed in air and at different concentrations of NO₂ in air, at selected temperatures.
