“…For decomposition of HD, GD and VX on nanocrystalline γ-Al 2 O 3 , TiO 2 , metal titanium and aluminum (Štengl V et al 2005 ) analogous degradation pathways have been suggested. Prasad et al ( 2010 ) , respectively. Nanoparticles of AP-Al 2 O 3 in the size range 2-30 nm with a surface area of 375 m 2 g −1 were produced by the sol-gel method and were used for studying the kinetics of HD adsorption (Saxena et al 2009 ).…”

Metal oxides have very important applications in many areas of chemistry, physics and materials science; their properties are dependent on the method of preparation, the morphology and texture. Nanostructured metal oxides can exhibit unique characteristics unlike those of the bulk form depending on their morphology, with a high density of edges, corners and defect surfaces. In recent years, methods have been developed for the preparation of metal oxide powders with tunable control of the primary particle size as well as of a secondary particle size: the size of agglomerates of crystallites. One of the many ways to take advantage of unique properties of nanostructured oxide materials is stoichiometric degradation of chemical warfare agents (CWAs) and volatile organic compounds (VOC) pollutants on their surfaces.

“…Prasad showed that it is possible to decontaminate (2-chloroethyl)phenylsulfi de (CEPS, simulant of sulfur mustard) with total (100 %) abatement and good selectivity to non-noxious by-products, using mixed metal oxide nanocrystals of Al 2 O 3 -Fe 2 O 3 , Al 2 O 3 -V 2 O 5 or Al 2 O 3 -CuO obtained by aerogel synthesis process [ 29 ]. Analogously, zinc titanate ceramic nanofi bers, in particular, with a ZnO-TiO 2 40-60 % composition, were proposed as active fi lters in face masks or protective clothing and have displayed a good detoxifi cation activity in the presence of paraoxon (as nerve CWA simulant) and of (2-chloroethyl)ethylsulfi de (CEES; another sulfur mustard simulant) [ 30 ] …”

The destruction of chemical hazardous agents can be required on the fi eld, for decontamination after an accidental or deliberate release, as well as in laboratories, pilot plants and chemical agent destruction sites, for abatement of stockpiled chemical weapons. Nanostructured inorganic metal oxides and/or metal particles, in all forms and formulations, constitute a large class of materials that are suitable for such purposes. They are robust, rich in specifi c surface sorption sites, active in the degradation of hazardous compounds via catalytic or photocatalytic mechanisms and, in most cases, relatively cheap. Such nanosystems show promising performances in terms of activity and selectivity, even at very low catalyst to toxic agent ratios. It is thus possible to move from conventional stoichiometric destruction to catalytic chemical decontamination of hazardous compounds. However, the recent ever-increasing concerns about the consequences on human health and environment of nanosized inorganic systems must induce a careful investigation about their toxicological and pathogenic impact on living organisms.
