以NASICON(钠超离子导体)固体电解质为离子导电层,Y2O3为敏感电极研制了一种用于测定CO的电化学气体传感器。结果表明,器件对(5~50)×10“范围内的CO具有较好的敏感特性。在400℃下,器件对CO的灵敏度为-45mV/decade。并且器件对CO具有较高的选择性和良好的响应恢复特性。
An electrochemical gas sensor was investigated for measuring CO using NASICON(sodium super ionic conductor) solid electrolyte as the ion conductive layer and Y2O3 as the sensing electrode. The results showed that the sensor exhibited well sensing characteristics to (5-50)×10^-6 CO. The sensitivity of the sensor to CO was -45mV/decade at 400℃. Also the sensor exhibited high selectivity and response-recovery performance to CO.
