Two-Dimensional (2D) Hybrid Nanocomposites for Environmental Sensing Applications

This chapter focuses on the development and application of 2D hybrid nanocomposites for environmental sensing. The unique properties of 2D materials, which include graphene, have made them promising candidates for environmental sensing applications. In particular, the incorporation of 2D materials into hybrid nanocomposites has made the manipulation of their optical, electrical, and mechanical properties for specific sensing applications, possible. An advantage of 2D hybrid nanocomposites for environmental sensing is their high sensitivity to various analytes, including gases, humidity, and chemicals. For instance, graphene-based hybrid nanocomposites have been proven to show high sensitivity to trace gases such as ammonia, nitrogen dioxide, and sulfur dioxide. In addition, 2D hybrid nanocomposites offer several advantages, including ease of fabrication and low cost. These materials can be synthesized using various methods such as chemical vapor deposition, solution processing, and physical vapor deposition. The chapter also discusses the challenges associated with the development of 2D hybrid nanocomposites, including the need for improved selectivity, stability, and reproducibility. Some future perspectives on the potential applications of 2D hybrid nanocomposites in environmental sensing are discussed, including their use in air and water quality monitoring and food safety.
