초록

$TiO_2$ nanowires were synthesized by hydrothermal method for the application to ethanol gas sensor. $TiO_2$ nanowires were decorated with Au nanoparticles to improve the sensitivity to ethanol gas. Scanning electron microscopy and Transmission electron microscopy revealed that the synthesized nanowires had diameters and lengths of approximately 100 - 200 nm and a few micrometers, respectively. Size of the Au nanoparticles decorated on the $TiO_2$ nanowires was observed to be in the range of 10 - 20 nm. X-ray diffraction confirmed that the decorated nanowires were composed of anatase-, rutile-$TiO_2$, and Au. The sensitivities of $TiO_2$ nanowires sensors decorated with Au were approximately 1.1 - 3.65 times as high as those of as-synthesized $TiO_2$ sensors for the ethanol concentration of 5 - 100 ppm at $200^{\circ}C$. The mechanism of the improved ethanol gas sensing of the $TiO_2$ nanowires decorated with Au nanoparticles is discussed.
