Graphene-based gas sensors have attracted significant attention due to advantages like high surface-to-volume ratio, excellent electrical conductivity, and good mechanical properties. Although great progress has been made in recent years toward improving the sensing performance of these sensors, still lack of selectivity and costly fabrication of graphene impose challenges toward the commercial application of these sensors. On the other hand, metal oxide nanowires (NWs) are well-established sensing materials for the detection of various oxidizing and reducing gases with excellent sensing properties and ease of manufacture. In this chapter, we shall discuss the application of metal oxide NWs and graphene-based hybrid structures toward the detection of various toxic gases at room temperature.
