Claims
- 1. A method of detecting carbon monoxide gas at a temperature of from -10.degree. to 100.degree. C., by using, as the only carbon monoxide gas detecting element, an element consisting of stannic oxide as the main component, antimony, and platinum, which element is prepared by mixing stannic oxide, antimony trioxide and platinum in atomic ratios of Sb/Sn=at least 0.005, Pt/Sn=at least 0.004 and Sb/Pt=at least 0.005, and sintering said mixture at a temperature of at least 625.degree. C.
- 2. A method according to claim 1, wherein said atomic ratios are Sb/Sn=0.005-0.1, Pt/Sn=0.004-0.2 and Sb/Pt=0.005-5.
