SO2 Gas Sensor Based on Al3 + and O2 – Ion Conducting Solids with La2 O2 SO4 Auxiliary Electrode
Abstract:A new solid electrolyte type sulfur dioxide (SO2 ) gas sensor was fabricated by the combination of trivalent aluminum cation conducting (Al0.2Zr8)20/19Nb(PO4)3 and divalent oxide anion conducting yttria stabilized zirconia (YSZ) with Li2 SO4-doped La2 O2SO4 as the sensing auxiliary electrode. The present sensor shows such a practical performance of a rapid, stable, continuous, and reproducible response at 500°C, and the linear relationship which obeys the Nernst relationship was clearly observed between the sensor EMF output and the logarithm of the SO2 gas concentration.
