摘要
在 Ｓｎ Ｏ２ 基体材料中掺杂 Ｔｈ Ｏ２ 及 Ａｕ， Ｐｄ 等贵金属催化剂，获得了２７０ ℃高温区域对 Ｃ Ｏ 具有高灵敏度的气敏元件．通过活性碳过滤技术，改善了该元件的选择性．测试结果表明，该元件具有良好的稳定性，是一种实用化的 Ｃ Ｏ气敏元件．
CO gas sensor was made by adding ThO 2 ,Au and Pd to SnO 2 powder, which has high gas sensitivity and character of rapied response and recovery and work at high temperature. Its gas selectivity to CO was improved by filtration of active carbon,the sensor has good long time stability,thus this gas sensor has good applicative fore ground.
