Room temperature carbon nanotube based sensor for carbon monoxide detection
Sulfonated single-walled carbon nanotubes have been used in an integrated electrode structure for the detection of carbon monoxide. The sensor responds to 0.5 ppm of CO in air at room temperature. All eight sensors with this material in a 32-sensor array showed good repeatability and reproducibility...

| Summary: | Sulfonated single-walled carbon nanotubes have been used in an integrated
electrode structure for the detection of carbon monoxide. The sensor responds
to 0.5 ppm of CO in air at room temperature. All eight sensors with this
material in a 32-sensor array showed good repeatability and reproducibility,
with response and recovery times of about 10 s. Pristine nanotubes generally
do not respond to carbon monoxide and the results here confirm sulfonated
nanotubes to be a potential candidate for the construction of an electronic
nose that requires at least a few materials for the selective detection of
CO. |
