This article provides an overview of the electrical and gas-sensing properties of reduced graphene oxide-metal oxide nanocomposites with improved sensitivity, selectivity, stability, and other sensing performances. It highlights the importance of exploring this area for the development of high-performance gas sensors.
From the past decade, there is a demand for the development of highly sensitive and selective, operating at low temperature, and stable gas-sensing materials used to monitor hazardous gases. The discovery of graphene has led to the implication of the same as gas sensor as it possesses large value of surface to volume ratio and high value of electron mobility at room temperature. Few researchers have fabricated reduced graphene oxide-metal oxide composite gas sensors exhibiting good electrical and gas-sensing properties. But still, it is a very less explored area. This article provides an overview of electrical and gas-sensing properties of reduced graphene oxide-metal oxide nanocomposites with improved sensitivity, selectivity, stability, and other sensing performances. This review is mainly focuses on reduced graphene oxide-metal oxide nanocomposite-based gas sensors which are cost-effective and sensitive to the various gases/vapors.
