Abstract:
TiO2 nanowires were synthesized by a hydrothermal process in KOH solution at 190°C using TiO2 powder as a source material. Characterizations indicate the high degree of crystallinity with diameter of ca. 10-20 nm and length in micrometer scale of the obtained TiO2 nanowires. Multiple nanowires gas sensors were fabricated by dispersing the TiO2 nanowires on an interdigit Pt-electrode. The TiO2 nanowires sensors show a high sensitivity to Liquefied Petroleum Gas (LPG) at working temperature of 400°C. The results demonstrate the possibility of using TiO2 nanowires for gas-sensing application. © 2009 IOP Publishing Ltd.
