Characteristics of Nanoparticles-Based Chemical Sensors


Semiconducting nanoparticle tin oxide-based sensors have been prepared with a pressure load of 4, 6, 8, 10 tons and reinforced with carbon nanofibers (CNF) in SnO2 matrix. The SnO2/CNF sensor’s sensitivity for ethyl alcohol has in-creased by a factor of two, in compared with that of pure SnO2 8-ton pressed sensor with lower response time. These results open the way towards further optimized lower cost CNF nanocomposite sensors as compared with expensive tin oxide/carbon nanotubes sensors.
