  • Patent number: 11524266
    Abstract: A composite material is provided comprising a porous polymeric matrix having metal-organic framework (MOF) domains dispersed within the porous polymeric matrix, each of said MOF domains in fluid communication with the external environment through the pores in the porous polymeric matrix. A process of using the composite material to chemically modify or detoxify a chemical warfare agent or a toxic industrial chemical is also provided. The chemical warfare agent or the toxic industrial chemical is brought into contact with a MOF domain within the porous polymeric matrix so that the MOFs adsorb and chemically modify the chemical warfare agent or the toxic industrial chemical.

Exemplary process for sensing a toxic chemical includes contacting a toxic chemical, or byproduct thereof, with a sorbent that includes a porous metal hydroxide or a porous mixed-metal oxide/hydroxide and a transition metal reactant suitable to react with a toxic chemical or byproduct thereof. The sorbent is contacted with the toxic chemical or byproduct thereof for a sampling time. A difference between a post-exposure colorimetric state of the sorbent and a pre-exposure colorimetric state of the sorbent is determined to thereby detect exposure to, or the presence of, the toxic chemical or byproduct thereof.

  • Patent number: 10495592
    Abstract: Provided are processes for the sensitive detection of the presence of, absence of, and optionally the identity of, one or more chemical agents. The processes use the binding of chemical agents to a metal organic framework or metal oxide/hydroxide electrically connected to a pair of electrodes to detect low levels of chemical in a sample. By exposing the surface of the metal organic framework or the surface of the metal oxide/hydroxide to the chemicals and then measuring changes in impedance magnitude and/or phase shift through electrical impedance spectroscopy, the presence of a chemical agent is readily detected.

  • Publication number: 20190083953
    Abstract: A high-surface-area, highly porous manganese oxide (MnOx) in the form of xerogel or aerogel monoliths or powders comprising a manganese oxide nanoarchitecture comprising an interior surface area >200 m2 g?1, wherein the MnOx gel has a void structure comprising pores that are sized from 2-150 nm, and wherein the manganese oxide nanoarchitecture removes toxic gas from a toxic gas and air mixture at room temperature via an oxidative mechanism that converts the toxic gas to an innocuous adsorbed substance. These high-surface-area, ultraporous manganese oxide (MnOx) xerogels and aerogels exhibit outstanding filtration performance for multiple, chemically distinct toxic gases, including ammonia, sulfur dioxide and hydrogen sulfide. These MnOx materials use multiple mechanisms for small molecule capture/catalysis including molecular sieving and oxidative decomposition, and function in a wide range of humidity conditions.
