| description | This paper reports a selective method of sensing hydrogen sulphide in gaseous state using silver nanoparticle
decorated single-walled carbon nanotubes (SWCNT) at room temperature. The transduction platform
is a simple resistor which was constructed by drop-casting of a random network of silver nanoparticle
decorated carbon nanotubes onto a channel joining two electrodes. This study shows the differential
sensing of hydrogen sulphide with respect to interfering analytes such as carbon monoxide and nitric
oxide, displaying the different mechanisms involved in the sensing of the gases. These results indicate
the possibility of fabricating simple devices with low power consumption based on flexible plastic substrate
for selective sensing of gaseous molecules at room temperature by appropriately functionalizing
the carbon nanotubes (CNTs). |
