Abstract
Gas sensors have attracted immense attention due to the requirement of controlled processes in the electronic, automobile, agricultural, and pharmaceutical industries. The sensing property of solid-state sensors depends on the surface area and surface chemistry of the sensor materials. In this respect, carbon nanotubes and their composites are ideal candidates for chemical sensing applications due to their large surface to volume ratio. Unlike pristine carbon nanotubes and graphene sensors, composites of CNT and graphene and reduced graphene oxide show greater selectivity toward the target gases. In this chapter a comprehensive discussion on the gas sensing property of carbon nanotubes, graphene/reduced graphene oxide and their composite devices are covered. Apart from this, widely used different types of carbon nanotube and graphene-based sensors are also discussed in detail. Synthesis and fabrication of nanotube sensors are highlighted with stress on resistive sensors. The challenge of fabricating a good gas sensor, i.e., a sensor with high sensitivity, low hysteresis, short response, and recovery time are addressed.
