Abstract

Pure Sn O2 and Sn O2 polycrystalline nanofibers doped with multiwall carbon nanotubes (MWCNTs) are synthesized by electrospinning followed by calcination in air at 500 °C. The measurement results by sensors fabricated from these fiber mats at steady state show that the n -type Sn O2 /MWCNT nanofibers are able to detect carbon monoxide at 50 ppm at room temperature, while the pure Sn O2 nanofibers are insensitive up to 500 ppm. The MWCNT doped Sn O2 nanofibers have demonstrated their potentials for wearable room temperature gas sensors with low cost and power consumption.
