New type of sulfur diozide gas sensor based on bivalent Al3+ ion conducting solid electrolyte
A new solid electrolyte type sulfur dioxide gas sensor was fabricated by the combination of the trivalent aluminum cation conducting (Al0.2Zr0.8)(20/19)Nb(PO4)3 solid and the divalent oxide anion conducting yttria stabilized zirconia (YSZ) with the NaAI(SO4)2 solid as a detecting auxiliary electrode. Since the present sensor showed such a superior sensing performance of theoretical response, which obeys the Nernst relationship between the sensor EMF output and the logarithm of the SO2 gas concentration, along with the stable, continuous, and reproducible response, it is greatly expected to be applied to a practical SO2 gas sensing device.
