| Description: |
ISSN: 2504-3900 ; International audience ; The development of selective and cheap metal oxide gas sensor at ambient temperature is still a challenging idea. In this study, SnO 2 surface functionalization was performed in order to obtain sensitive and selective gas sensor operated at ambient temperature. 3-aminopropyltriethoxysilane (APTES) was used as an intermediate step, followed by functionalization with molecules having acyl chloride with different end functional groups molecules such as alkyl, acid and ester groups. Acid and ester modified sensors are sensitive to ammonia between 0.2 and 10 ppm at room temperature. However, ester modified SnO 2 is more selective than acid modified sensor regarding ethanol and carbon monoxide gases. |
