Abstract
The abatement of toxic chemical warfare agents (CWA) is conventionally achieved via stoichiometric reactions using strong oxidants with high environmental impact and/or via thermal degradation. The international Project “NanoContraChem”, in the framework of NATO Science for Peace and Security Programme, aims at obtaining innovative nanostructured inorganic materials for the catalytic decontamination of CWA. In the first year of activity, a class of heterogeneous catalysts has been designed to transform selectively and under mild conditions toxic organosulfur chemical agents in non-noxious products with reduced environmental impact. Nb(V)-containing saponite clay was identified as an optimal catalyst for the CWA oxidative abatement. The conventional synthetic protocol used to obtain saponite materials was modified to allow the insertion of Nb(V) ions within the inorganic framework of the clay, thus obtaining a bi-functional catalyst with strong oxidizing and acid properties.
