） Abstract： One-dimensional titania nanotube arrays were prepared in the electrolyte containing F- via electrochemical anodization method
FESEM analysis indicated that 1
2µm length TiO2 nanotubes were obtained at anodizing voltage 20V for 2h, and the average pore diameter and wall thickness came to 60nm and 30nm
A possible growth mechanism of titania nanotube arrays was simply presented
TiO2 nanotube arrays annealed at 500°C in an oxygen atmosphere showed good sensitivity to acetone vapor
The sensitivity changed with the testing temperature and the concentration of acetone vapor
The sensitivity to 120ppm acetone gas was 298 at the testing temperature of 270°C
The titania nanotube arrays can be a promising option for microconcentration of acetone gas sensors used for medical detection
