  • Patent number: 10732098
    Abstract: Processes, compositions, and sensors for sensing a variety of toxic chemicals based on colorimetric changes. 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: 10625239
    Abstract: Provided are mixed metal oxy-hydroxides that serve as reactive media to bind, sequester, or alter one or more toxic chemicals such as sulfur dioxide (SO2), hydrogen cyanide (HCN), and others. A reactive media includes: a porous metal oxy-hydroxide including at least one first transition metal that is optionally one or more of copper, zinc, or iron; a second transition metal linked to the first transition metal by a bond that includes an oxygen, the second transition metal selected optionally being one or more of magnesium, calcium, cobalt, titanium, zirconium, aluminum, and silicon; and the metal oxy-hydroxide terminated by at least one hydroxyl group. The resulting media provides for excellent porosity and reactivity for removal of toxic chemicals from the environment or a sample.

  • 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.

  • Patent number: 10261022
    Abstract: Processes for sensing a variety of toxic chemicals and/or processes for determining the residual life of a filter or filtration system are provided. Exemplary process for sensing a toxic chemical include contacting a toxic chemical, or byproduct thereof, with a sorbent that includes a porous metal 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 or control is determined to thereby sense exposure to, or the presence of, the toxic chemical or byproduct thereof.

  • 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.
