Graphene, one atom thick allotrope of carbon, has enabled researchers to a new era of exploration due to its unique properties. Graphene is considered to be mother of all carbon materials with excellent electrical, mechanical, optical, and thermal properties that made its use for various engineering applications. Graphene and graphene hybrids have proved over the last decade to be promising material for chemical sensors. High surface-to-volume ratio coupled with high conductivity enabled graphene-based sensors to perform well with high accuracy, high sensitivity and selectivity, low detection limits and long-term stability. To further enhance the properties of graphene, graphene-based hybrids have been synthesized for its use as transducing element in various chemical sensors such as gas and biosensors. These hybrids exhibit the synergistic benefit for both the material for fabrication of efficient sensors with enhanced performance. This chapter focuses on synthesis, characterization and applications of various graphene hybrids in chemical sensors.
