Photocatalytic oxidation of VX simulant 2-(butylamino)ethanethiol

Titanium dioxide photocatalysis to decompose isopropyl methylphosphonofluoridate (GB) in gas phase

“…For CWAs simulant, dimethyl sulfide (DMS), diethyl sulfide (DES) and 2-chloroethyl ethyl sulfide (2CEES) as 2,2 -dichloro diethyl sulfide (sulfur mustard: HD) simulant as a blister agent [18][19][20][21][22][23][24][25][26][27][28], and dimethyl methyl phosphonate (DMMP) [34][35][36][37][38][39][40][41][42][43] and di-isopropylfluorophosphate (DFP) [44,45] as isopropyl methylphosphonofluoridate, Sarin (GB) and trimethylpropyl methylphosphonofluoridate, tabun (GD) simulant as a nerve agent have been known for major simulants. Complete decomposition of these simulants by TiO 2 photocatalysis and the detailed decomposition mechanism at the surface of TiO 2 photocatalyst are well elucidated and widely known.…”

Removal of malodorous organic sulfides with molecular oxygen and visible light over metal phthalocyanine

“…Although these methods have their own advantages, the operation cost is high or the process produces a large amount of wastes that require further treatment [4]. Recently TiO 2 photocatalysis has been successfully applied for destruction of organic sulfides [5][6][7]. However, the system needs to be excited with UV light, which occupies only about 5% in the sunlight reaching on the earth surface.…”

Photocatalytic decomposition of acephate in irradiated TiO2 suspensions

“…Thiosulfonate is not stable in aqueous solution and disproportionates into starting disulfide and thiosulfonate. Vorontsov et al [16,22] deeply investigated the degradation of 2-PECES (2-phenethyl-2-chloroethyl sulfide) in irradiated TiO 2 suspensions and found the similar reaction mechanism for C 6 H 5 CH 3 S(O) 2 SCH 3 C 6 H 5 . Xu et al [7] also detected CH 3 S(O) 2 SCH 3 during the photocatalytic degradation methamidophos.…”

“…Although methamidophos could also be protonated under acidic condition, N-P bond would be broken by hydrolysis reaction. Vorontsov et al [12,16] analyzed the products of photocatalytic degradation of DEPA ((C 2 H 5 O) 2 P(O)NH 2 ) and found that the cleavage of P-N bond was the main mineralization pathway of DEPA. So, CH 3 O(CH 3 S)P(O)OH and NH 3 would be formed in principle.…”

“…Additionally, photocatalytic degradation of mixed sulfur-nitrogen functionalized organics has hardly been reported in detail yet. Research with such compounds presents interesting features [16].…”
