摘要： 研制了一种新的SnO2掺CeO2的CO气敏元件;对其在不同温度下对不同气体的气敏特性进行了测定.结果表明,该种气敏元件在较低温度(115℃)时对CO具有高灵敏度、高选择性以及快速响应等特点.对此结果进行了简单的讨论.

Abstract: A new type of CO gas sensor of SnO2 doped CeO2 has been made. The sensing characteristics of this sensor have been examined for several gases at different temperatures. The results show that the sensor achieves high sensitivity, excellent selective detection and short response time for CO at a low temperature (115℃). The results are also discussed.
