ABSTRACT
The analytical detection of hydrogen sulfide (H2S) has received great attention owing to its toxic nature as well as its important regulatory roles in modulating the nervous system. It also has significance for the metabolic pathways in mammalian cells. Metal-organic frameworks (MOFs) have been used in different sensors owing to their high surface area, porosity, electrical conductivity combined with robust chemical kind of stability, and/or charge mobility. MOFs have been applied to the sensing of H2S in limited techniques such as luminescent, capacitive, and resistive-based sensors. This chapter discusses the recent trends in the application of MOFs ins capacitive and resistive sensors for H2S. The H2S adsorption mechanism in MOFs has been discussed in order to gain an understanding of the sensing mechanism in MOF-based capacitive and resistive sensors. The chapter ends with a conclusion discussing the present status along with a small discussion on future perspectives.
