摘要：
A carbon dioxide gas sensor was fabricated by the combination of trivalent Al3+ cation conducting (Al0.2Zr0.8)(20/19)Nb(PO4)(3) and O2- anion conducting yttria stabilized zirconia (YSZ) with the two phase mixture of 0.5(0.8La(2)O(2)SO(4)-0-2Li(2)CO(3)) + 0.5(Nd0.47Ba0.12Li0.29)O0.94CO3 solid as the sensing auxiliary electrode. Since the present sensor shows a quantitative and reproducible response, which exactly obeys the Nernstian theoretical relationship at 500 degrees C, it is greatly expected that the present sensor would be one of the promising candidates for the practical CO2 sensing devices applicable at intermediate temperature range around 500 degrees C.
