Enhanced response and sensing speed of Au-functionalized WO3 nanotubes toward NO2 gas |
| 초록 |
Au-functionalized WO3 nanotubes were synthesized using ZnO nanowire templates. Transmission electron miccroscopy revealed the Au nanoparticles on the outer surface of a typiclal WO3 nanotube ranged from 5 to 25 nm. The multiple networked Au-functionalized WO3 nanotube sensors showed responses of 820 - 3,924% in the NO2 concentration range of 1 - 5 ppm at 300°C. These responses are far superior to those of pristine WO3 NTs and most other oxide one-dimensional nanostructures reported in the literature. The underlying mechanism for the enhanced gas sensing properties of Au-functionalized WO3 nanotubes is discussed. |
