NICKEL-MODIFIED CARBON NANOTUBE AS CH4, H2S, AND NO GAS SENSORS
Functionalization of single-walled carbon nanotube (SWCNT) is an attractive platform as gas sensor devices. This study introduce Nickel (Ni) modifications, e.g. as dopant, adatom, and cluster, to (5,5) and (10,0) SWCNT as CH4, H2S, and NO gas sensor. The presence of Ni atoms basically modify the ele...

Functionalization of single-walled carbon nanotube (SWCNT) is an attractive platform as gas sensor devices. This study introduce Nickel (Ni) modifications, e.g. as dopant, adatom, and cluster, to (5,5) and (10,0) SWCNT as CH4, H2S, and NO gas sensor. The presence of Ni atoms basically modify the electronic properties of those CNTs. Pristine CNTs have low ability to adsorb and distinguish those gases. Meanwhile, the Ni-cluster-modified-CNT shows excellent response to adsorb and distinguish the sample gases. In addition to that, Ni-cluster leads to the dissociation of H2S gas. We also obtain that Ni-modified CNTs are able to reveal and distinguish the sample gasses at room temparature. In particular, based on the electric conductivity response, the semiconducting based CNT shows significant performance while detecting NO gas. These results may then contribute to the further development of SWCNTs based chemiresistor device. |
