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

The present invention relates to single thread composite fibers comprising at least one binder and at least one active catalyst for the capture and degradation of chemical threats such as chemical warfare agents (CWA), biological warfare agents, and toxic industrial chemicals (TIC) and a method for producing the same. The invention fibers are applicable to the fields of protective garments, filtration materials, and decontamination materials.

A polymer-based material includes a polymeric binder and one or more porous active materials that adsorb, chemisorb, decompose, or a combination thereof, a hazardous chemical. The polymeric binder and the one or more porous active materials are combined to form a composite bead. The polymeric binder may include a polyurethane or a styrene-based block copolymer. The porous active materials may comprise metal-organic frameworks, metal oxides, metal hydroxides, and metal hydrates. The one or more porous active materials may be between 1 and 99 wt % of a total composite mass of the composite bead. Alternatively, the one or more porous active materials may be between 80 and 95 wt % of a total composite mass of the composite bead. The hazardous chemical may include a chemical warfare agent, a simulant of chemical warfare agents, and toxic industrial chemicals.

A system for breaking down a PFA (perfluoroalkyl or polyfluoroalkyl) compound includes a reactor vessel, a heater, and a catalyst. The reactor vessel is operable to hold influent that includes a PFA compound, an alkali, and water, while alkaline hydrolysis separates a fluorine atom from the PFA compound in the influent. The heater is operable to heat the influent to a temperature within the range of 100? Celsius to 700? Celsius. And the catalyst is operable to increase the rate at which alkaline hydrolysis separates a fluorine atom from a PFA compound. The catalyst includes a body that includes a transition metal, which is a d-block metal or a metal from any of the periodic table's groups 4-11. The body also has a shape configured to multiply a surface-area-to-volume ratio by at least 1.5 when the body is disposed in an influent experiencing alkaline hydrolysis.
