  • Solid-state gas sensor for carbon monoxide and hydrogen
    Patent number: 5439580
    Abstract: Anatase titania is used as the sensitive ceramic for sensing the amount of carbon monoxide and hydrogen in mixed gasses where the changes in electric current characteristics passing through such ceramic when it is exposed to such gases is used to determine the amount of carbon monoxide and hydrogen present. Such sensor is made selective to hydrogen when alumina is included in the ceramic and to carbon monoxide when yttria is included. Additions of a catalytic metal particularly iron or palladium is beneficial to the anatase titania-yttria ceramic in its selective sensing of carbon monoxide.
