A series of SnO2–CeO2 powder mixed oxides (with 5, 10, and 20 % wt SnO2) was prepared, characterized and used to study the sensing properties for CO, in absence of oxygen, using a CO-helium mixture. The results have shown that the SnO2–CeO2 powder has good response and recovery characteristics. This powder has better sensitivity to CO than pure SnO2 at the working temperature of 400–450 °C. A sensing mechanism was proposed and discussed in this paper. The results have indicated that the SnO2–CeO2 mixed oxides can be used as CO sensors, in absence of oxygen.
