compared to its response to CO2, CH4, and C3H8, thus the sensor is considered to be selective for CO under these test conditions.

For the past decade, the
of the sensor increases from 210 to 300 °C. Given that the sensing results are reproducible, the sensor may be proposed for further development which may result in a commercial sensor for selectiveCOdetection.
The composite sensor, S4, containing 2 wt % ZnO and 98 wt % SnO2 exhibited a very high
