Abstract

Chemical substances in gaseous state are often extremely hazardous, especially when present in concentrations above the prescribed safe limit. Gaseous chemicals reach the open environment under various circumstances, including gas leakages, uncontrolled emission of gaseous effluents from industries, transportation vehicle exhausts, burning and combustion, etc. The situation gets even more serious in indoor environments and densely populated areas. Therefore, proper control and monitoring is essential to prevent gas exhaust and detect the trace of exhausted gases at the earliest possibility, in order to bring in immediate remediation and ensure safety of the environment and our health. In this scenario, gas sensors are playing a vital role. There are different categories of gas sensors, among which those based on metal oxides and sulfides have received very high attention owing to their high-performance level, cost-effectiveness, and wide applicability.

This chapter will present different types of metal oxide- and sulfide-based gas sensors, and the interesting results obtained from their operations, that have been developed in the last 5 years (i.e., 2014–2019). This 5-year period has been chosen in order to present to the readers the very recent trends and developmental aspects in this particular area of research. Overall, this research area is very well-studied, as evidenced from the huge number of reports that get published every year for a period of over three decades. Therefore, this chapter does not aim to present exhaustive literature review. The main focus will be to dish out to the readers selective interesting research and developmental reports that have been published in the field of metal oxide- and sulfide-based gas sensors in the last 5-year period.
