Gas sensors have been widely used to monitor leakages and control the concentrations of various gases, during the production and fabrication processes of industrials. Conventional gas sensors were based on semiconducting oxides, such as SnO2, ZnO, Fe2O3 and In2O3. Recent development revealed that nanocarbons, including carbon nanotubes (CNTs) and nanosheets of graphene nanosheets, carbon nanofibers and carbon black, exhibit strong high performance gas sensing behaviors. Furthermore, gas sensing performances the nanocarbon materials can be enhanced by forming hybrids with nanoparticles of noble metals and semiconducting oxides. This review paper was aimed to provide an overview on recent progress in the development and characterization of gas sensors based these nanocarbon materials and their hybrids.
