Advanced Functional Nanomaterials for Explosive Sensors

Abstract

This chapter reviews the recent advances, difficulties, and challenges in the detection of explosives. The nitro-based explosive materials such as dinitrotoluene (DNT), trinitrotoluene (TNT), and picric acid are used for the production of explosives. There are various methods such as mass spectrometry (MS), ion mobility spectrometry (IMS), and gas chromatography (GC) which are used for the detection of such compounds

however, most of these devices are bulky and expensive and require time-consuming procedures. The electrochemical method is considered the most reliable, highly sensitive, selective, and low cost which possesses advantages over conventional methods. To construct a highly sensitive and selective electrochemical sensor, metal oxide-based nanomaterials have been immobilized onto the active surface area of the different electrodes (glassy carbon, gold, FTO, ITO, platinum, and graphite). The goal of this chapter is to review recent advances in electrochemical detection of nitro-containing explosive at working electrode consisting of different nanomaterials

specially, we will discuss the role of graphene and graphene-containing metal oxide composites for the detection of nitroaromatic compounds. © Springer Nature Switzerland AG 2021. All rights are reserved.
