Reactions of the mustard simulant 2-chloroethyl phenyl sulfide with self-decontaminating sorbents. A 13C MAS NMR study

Modified titania nanotubes for decontamination of sulphur mustard

“…Reaction with surface -O-H and Ti 4+ sites and intercalated water could have been the decontamination mechanism in them. These results show that, Ag + -titania nanotubes exhibited promising results on par with the existing solid decontamination systems such as nanosized MgO, Al 2 O 3 , etc., and original untreated nanotubes [7][8][9][10][11][12][13][14][15].…”

“…Owing to their large surface area, wider pore structure, they adsorb the liquid agent strongly into their pores and remove it from contaminated surfaces [1][2][3][4]. After adsorption, chemical functionalities like defects or acid, base sites react with CWAs by means of hydrolysis, elimination and oxidation reactions and convert them into non-toxic products [5][6][7][8][9][10][11][12][13][14][15]. Nanosized particles have a tendency to form aggregates thereby making their surface unavailable for adsorbate molecules.…”

Nanocrystalline zinc oxide for the decontamination of sarin

“…Recently, aero gel prepared metal oxides of MgO, CaO and Al 2 O 3 were found to promote hydrolysis reactions of sarin, a deadly chemical warfare agent and converted it into non-toxic product called methyl phosphonic acid. These reactions were studied at room temperature by the MAS-NMR and the data illustrated destruction reaction of the sarin with a half-life of 1.8 h on AP-Al 2 O 3 [6][7][8][9][10][11][12].…”

Decontamination of sulfur mustard and sarin on titania nanotubes

“…12 However, nanotubes of metal oxides orient typically and randomly to keep their charge, steric balances, and pore connectivity intact thereby providing large surface area and promising wider adsorption and decontamination related applications. [13][14][15] Recently Ma et al, 16 Kasuga et al, 17,18 and Chen et al 19 have prepared nanotubes of TiO 2 , MnO 2 , Ca 3 Nb 3 O 10 , and K 4-x H x Nb 6 O 17 by soft chemical and hydrothermal methods. Among them, TiO 2 nanotubes have got immense importance because of their exceptional photocatalytic and CW agent decontamination properties.…”
