Abstract
With the advances in technology and demand of advanced functional devices, several industries require efficient gas sensors for process control units, fabrication, and environmental monitoring. Carbon-based nanomaterials (CBN), especially carbon nanotubes and graphene, have shown promising sensor response because of its large area of contact and extraordinary electrical, thermal and mechanical properties. Carbon nanomaterials-based gas sensors exhibit high selectivity, high sensitivity, room-temperature operation, and lower detection limits with low response and recovery time as compared to conventional gas sensors. Specific functionalization and doping have been done to attain selectivity and high sensitivity toward particular gas with maximum gas response. Nanocomposites of CBN with several metal oxides, semiconducting metal oxides, and polymers in the past were explored for enhanced gas sensing capabilities. Several fabrication techniques are developed for highly efficient gas sensors based on CBN.
