广谱性CO气敏元件的研制

Preparation of the Multi-spectrum CO Gas Sensor

作者以γ Fe2 O3 为基料 ,通过Au2 O3 、PdO两种氧化物的复合掺杂 ,研制出了高灵敏度的CO广谱性气敏元件 。

The multi-spectrum CO gas sensor is made with γ-Fe 2O 3 material and Au 2O 3-PdO dopant. The sensitivity to CO is up to 8. At the same time, the sensitivity to C 4H 10 or H 2 is also up to 8 too, and the value is much bigger for C 2H 5OH. At last, the catalysis principle is discussed.
