二氧化碳气体传感器由三价Al3+阳离子导电(Al0.2Zr0.8)20/19Nb(PO4)3和O2−阴离子导电氧化钇稳定氧化锆(YSZ)与两相混合物组合而成。 0.5(0.8La2O2SO4–0.2Li2CO3)+0.5(Nd0.47Ba0.12Li0.29)2O0.94CO3固体作为传感辅助电极。由于本传感器在 500°C 时表现出定量且可重复的响应，完全遵循能斯特理论关系，因此非常期望本传感器将成为适用于 500°C 左右中间温度范围的实用 CO2 传感装置的有希望的候选者之一。
A carbon dioxide gas sensor was fabricated by the combination of trivalent Al3+cation conducting (Al0.2Zr0.8)20/19Nb(PO4)3and O2−anion conducting yttria stabilized zirconia (YSZ) with the two phase mixture of 0.5(0.8La2O2SO4–0.2Li2CO3)+0.5(Nd0.47Ba0.12Li0.29)2O0.94CO3solid as the sensing auxiliary electrode. Since the present sensor shows a quantitative and reproducible response, which exactly obeys the Nernstian theoretical relationship at 500°C, it is greatly expected that the present sensor would be one of the promising candidates for the practical CO2sensing devices applicable at intermediate temperature range around 500°C.
