Abstract: A new type of CO gas sensor of SnO2 doped CeO2 has been made. The sensing characteristics of this sensor have been examined for several gases at different temperatures. The results show that the sensor achieves high sensitivity, excellent selective detection and short response time for CO at a low temperature (115℃). The results are also discussed.
