Modern Decontaminants for Chemical Warfare Agents: Part I – Zeolites and Metal-Organic Frameworks (MOF)

D. Tušek, I. Cetina and V. Pehar

Abstract

The modern decontaminants for chemical warfare agents must be effective and environmentally acceptable. For these reasons, recent scientific research has focused on the investigation of the efficacy of metal oxides, natural and synthetic zeolites and metal-organic frameworks (MOF) in decontamination of chemical warfare agents and other toxic compounds such as organophosphorus pesticides. Although the first zeolite decontaminants research have been directed to the investigation of synthetic zeolites, the natural zeolites have become more interesting, especially clinoptilolite. It has been shown that zirconium-based metal-organic frameworks (MOF) can successfully break down chemical warfare agents and their simulants and be among the fastest catalysts for the hydrolysis of nerve agents. Development of modern decontamination materials is not intended only to exploring decontamination properties, but also in development of protective coatings and layers with a self-decontamination effect.
