study on catalytic and photocatalytic decontamination of (2-chloroethyl) phenyl sulfide with nano-tio2

catalytic and photocatalytic reactions of (2-chloroethyl) phenyl sulfide (2-ceps), a mimic of bis (2-chloroethyl)  sulfide (i.e. sulfur mustard) were studied on the surfaces of titanium oxide. tio2 nanoparticles (anatase, rutile and mixture of 80% anatase/20% rutile) along with bulk tio2 were tested as reactive sorbents for reaction of 2-ceps at room temperature (25±0.5°c). reactions were monitored by gc-fid technique and reaction products were characterized by gc-ms. data explores the role of hydrolysis and elimination reactions in the reaction of 2-ceps on titanium oxide. in these reactions, 2-ceps undergo photocatalytic reactions to yield  (2-hydroxyethyl) phenyl sulfide, (2-ethoxyethyl) phenyl sulfide and vinyl phenyl sulfide. also data reveals that the maximum decontamination of 2-ceps was related to nano-tio2 (80% anatase/ 20% rutile)/ uv.
