Abstract: Pure SnO₂and SnO₂polycrystalline 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 SnO₂/MWCNT nanofibers are able to detect carbon monoxide at 50 ppm at room temperature, while the pure SnO₂nanofibers are insensitive up to 500 ppm. The MWCNT doped SnO₂nanofibers have demonstrated their potentials for wearable room temperature gas sensors with low cost and power consumption.
