Abstract EN
Gas sensors for ethanol and acetone based on ZnO nanobelts with doping element indium were fabricated.
Excellent sensitivity accompanied with short response time (10 s) and recovery time (23 s) to 150 ppm ethanol is obtained.
For In-doped sensors, a minimum concentration of 37.5 ppm at 275°C in acetone was observed with an average sensitivity of 714.4, which is 7 times larger than that of the pure sensors and much larger than that reported response (16) of Co-doped ZnO nanofibers to acetone.
These results indicate that doping elements can improve gas sensitivity, which is associated with oxygen space and valence ions.
In-doped ZnO nanobelts exhibit higher sensitivity to acetone than that to ethanol.
These results indicate that doped ZnO nanobelts can successfully distinguish acetone and ethanol, which can be put into various practical applications.
