ABSTRACT
Hydrogen sulfide (H2S) is highly toxic, hazardous to humans, and responsible for flammable gas pollution from industries, similar to various other toxic gases. However, H2S is employed in various applications owing to its facile reactivity with oxygen, nitro, and azide compounds. Selective removal of toxic gases is necessary to ensure that they do not come into contact with the atmosphere. Various techniques such as adsorption, electrochemical, optical, and fluorescent sensing have been used to detect and selectively remove H2S. Various metal-based porous MOFs synthesized using different approaches have attracted significant attention for the sensing and selective detection of H2S over various other toxic gases. In this chapter, we exclusively discuss the use of SMOs and MOFs for the selective and sensitive detection of H2S.
