Indium oxide-based gas sensor for selective detection of CO
- Kyushu Univ., Fukuoka (Japan); and others
A compact solid-state CO sensor has been eagerly desired for detecting incomplete combustion of gas appliances, because continuous monitoring of CO in combustion exhausts can prevent a serious CO poisoning accident from occurring. The relevant sensor should be not only highly sensitive to CO but also selective to CO against various coexistent gases such as H{sub 2}, CH{sub 4}, C{sub 3}H{sub 6}, CO{sub 2}, NO and water vapor. In addition it should at the temperature of the exhausts (200-400 {degrees}C). In order to develop such a CO sensor, an extensive search was carried out for semiconducting oxides and modifiers. As a result, an In{sub 2}O{sub 3}-based sensor modified with Rb{sub 2}O was found to be sensitive and selective to CO at 300-400 {degrees}C, as described below.
