Germanium-doped titania semiconductors, which are capable of photocatalyzed electron transfer are coated with electronic deficient fluorinated phthalocyanines capable of energy transfer. The combination of these pathways results in a broad spectrum photocatalyst useful for deactivating harmful chemical and biological agents.

The present invention is directed to an aqueous nanofluid composition and the method of use thereof for displacing or removing chemical warfare agents (CWAs) from capillary spaces, the nanofluid composition comprising water, colloidal silica, and at least one surfactant, such that the nanofluid composition is adjacent to the capillary features to absorb the CWAs from the capillary features. Upon displacement or removal, the CWAs are ready for disposal.

Provided are MOF-fabric composites having a crystalline MOF adhered directly to fibers of the fabric and methods of making MOF-fabric composites. A solution is adsorbed onto a fabric. The solution can include a metal salt, a linker, and a solvent. The solution is adsorbed onto the fabric and the fabric suspended over a heated vapor. The vapor releases onto the fabric, causing the metal salt, the linker, and the solvent to diffuse out of the polymer fibers. The linker links metal from the metal salts to form crystals attached to the fabric, and the vapor aids crystallization.

A decontamination coating and method for manufacturing the decontamination coating, wherein the decontamination coating includes a multilayer structure including a support, a trapping layer intended to be brought into contact with the toxic chemical compounds so as to trap them, and a holding film intended to maintain the shape of the support in the plane and in a direction transverse to the plane, during the formation of the trapping layer.

Textile fibers at least partially coated with a coating that includes particles of metal-organic frameworks dispersed in a polymeric base are provided. Also provided are fabrics formed from the textile fibers, protective gear and articles of clothing made from the fabrics, and methods of using the fibers and fabrics to catalyze the hydrolysis of organic molecules, such as organophosphate-based nerve agents, having hydrolysable bonds.

Materials for decontamination of compounds having a phosphorous-sulfur bond or a phosphorous-oxygen bond. A porous polymer, such as poly(dicyclopentadiene), contains particles of zirconium hydroxide. The polymer optionally has hydroperoxide groups.

A metal organic framework (MOF)-polymer composite for detoxifying a chemical warfare agent (CWA) comprises MOF nanoparticles having catalytically active Lewis acid sites and at least one polymer having catalytically active basic sites. The composite is configured such that the at least one polymer is in surrounding relation to the MOF nanoparticles such that at least a portion of the Lewis acid sites of the MOF nanoparticles are in proximal relation to at least a portion of the basic sites of the at least one polymer thereby forming a plurality of proximal acid-base interfaces thus enabling a bifunctional catalytic mechanism for detoxifying the CWA. The MOF-polymer composite can provide CWA detoxification without the presence of a basic compound.
