Nanostructured Carbon-based Materials For Gas Sensor Applications

Goldoni, Andrea (Elettra, Trieste, ITA)

Here we present the nano-structured carbon based materials for sensors applications. Characteristics that suggest nano-structures as promising candidate for extremely sensitive gas sensors are the high-active surfaces and high- aspect ratios as well as the low cost of production and the large changes in the electronics properties due to a very tiny external perturbations. Moreover, possible integration in everyday life devices with scalability and portability will be another application to take into consideration. Carbon Nanotubes, carbon/metals and carbon/metal-oxides nanosystems are quite interesting to produce chemiresistor gas sensors with high sensible (sub-ppm), stable and a fast recovery time for environmental monitoring
