A critical review on emerging photoactive porous materials for sulfide oxidation and sulfur mustard decontamination

Abstract

Chemical warfare agents (CWAs) have been classified as fatal weapons of mass destruction because of their toxicity and deadly consequences. Among other CWAs, sulfur mustards (HDs) were employed during the...

A miniaturized ozonolysis flow platform for expeditious sulfur mustard warfare simulant neutralization

“…Documentation of these research domains has been steadily growing. [8][9][10][11][12][13] Protocols for the neutralization and/or destruction of HD are designed to impede the formation of an electrophilic episulfonium species, epi-HD, which is linked to the acute toxicity of sulfur mustards (Fig. 1a and b).…”

Selective and Efficient Detoxification of Sulfur Mustard Gas Analogues with H2O2 Using Bioinspired Mo and W Dithiolene Catalysts

“…Ideally, such a catalytic process would also employ a green oxidant (i.e., O 2 or H 2 O 2 ) that produces no chemical waste streams. 6 Compounds including strong acids, molecular metal complexes, polyoxometalates (POMs), and metal oxide solids have been explored as catalysts for oxidation of the SM research analogue, 2chloroethyl ethyl sulfide (CEES). 2 Photoactive porous materials, 6 especially metal−organic frameworks (MOFs), 7 have received significant attention for their ability to catalyze selective CEES oxidation to 2-chloroethyl ethyl sulfoxide (CEESO) under ultraviolet (UV) or visible light-mediated conditions via 1 O 2 generation.…”

“…Thus, SM detoxification requires a catalyst precisely tuned to promote the sluggish oxidation of SM to SMO without further oxidation to SMO 2 (Figure a). Ideally, such a catalytic process would also employ a green oxidant (i.e., O 2 or H 2 O 2 ) that produces no chemical waste streams . Compounds including strong acids, molecular metal complexes, polyoxometalates (POMs), and metal oxide solids have been explored as catalysts for oxidation of the SM research analogue, 2-chloroethyl ethyl sulfide (CEES) .…”
