Abstract

The methods for manufacturing NO₂ sensors from carbon-tin nanoparticle composites and the results of detection of NO₂ impurities in the range of 10–40 ppm in air are presented. All sensors operate at room temperature. The sensors with arc discharge soot and tin nanoparticles demonstrate the highest sensitivity. A combination of the graphene and SnO nanoparticle layers demonstrates the lowest response time. The interaction mechanisms of sensors with low NO₂ concentrations are discussed.
