摘要：

以NASICON(钠超离子导体)固体电解质为离子导电层，C02O3为敏感电极研宄了用于检测甲醇气体的电化学传感器。结果表明，器件对体积浓度为(100~1000)x10-6(体积分数，下同)内的甲醇气体具有较好的敏感特性。在300 蚓时，器件对浓度为120X10-5的甲醇的灵敏度为-145 mV,对浓度为(100, 300, 500) X10-5的甲醇的响应时间为30, 22, 10 s,恢复时间为50, 75, 105 s。并且器件对甲醇具有较高的选择性和良好的短期稳定性。

An electrochemical gas sensor was investigated with NASICON (sodium super ionic conductor) solid electrolyte as a ion conductive layer material and Co2〇3 as a sensing electrode for the measurement of methanol. The results show that the sensor exhibits superior sensing characteristics to (100-1000)^10^ methanol. The sensitivity of the sensor to 120x10^ methanol is 145 mV at 300 C. The response and recovery time to (100, 300 and 500) x10^ methanol was 30, 22 and 10 s and 50, 75 and 105 s, respectively. Also, the sensor has a high selectivity and a good short-term stability to methanol.
