Abstract Photocatalytic detoxification of sulfur mustard was studied on vanadium ion doped titania nanocatalysts under the irradiation of sunlight. Data obtained on vanadium ion doped titania nanocatalyst was compared with that of bare and commercial TiO 2 nanocatalysts. Vanadium ion doped titania nanocatalyst was found to be more active than bare and commercial titania nanocatalysts towards the photocatalytic detoxification of sulfur ...
