GAS SENSOR AND METHOD OF FABRICATING THE SAME |
| 摘要 |
A gas sensor and a method of fabricating the same are provided. The gas sensor includes a substrate, carbon nanotubes (CNTs) adsorbed onto the substrate, platinum nanoparticles (NPs) decorated to surfaces of the CNTs, and an electrode formed on the substrate onto which the CNTs with the platinum NPs decorated thereto are adsorbed. When the platinum NPs and CNTs are used as a sensing material, the gas sensor can be useful in sensing gases with high sensitivity even when present at a low concentration of at least 2 ppm and stably sensing noxious gases such as C6H6, C7H8, C3H6O, CO, NO, and NH3 as well as NO2, and can have particularly excellent selectivity and response characteristics with respect to NO2 gas. |
