Abstract: Decontamination reactions of chemical warfare agent (CWA) simulants (2 chloro ethyl phenyl sulphide and dimethyl methyl phosphonate) on silver ion exchanged titania nanotubes (Ag+-TiO2 NT) were studied by gas chromatography (GC). Nanotubes (NTs) were synthesized using hydrothermal-ion exchange method and characterized by SEM-energy dispersive analysis of X-rays, N2 BET, X-ray diffractometry and thermogravimetry. Formation of hydroxy ethyl phenyl sulphide and methyl phosphonic acid exemplified the role of hydrolysis reactions in decontamination of CWA simulants. Reactions seemed to occur considerably faster on Ag+-TiO2 NT indicating catalysis by Ag+.
