  • Sol-gel synthesis of max phase functional materials
    Patent number: 12227422
    Abstract: Preparing MAX phase structures includes forming a gel including a transition metal M, a Group 3A or Group 4A metal or semimetal A, and an acidic chelating agent or gelling agent X. X includes one or both of carbon and nitrogen. Preparing the MAX phase structures further includes shaping the gel to yield a shaped gel and heating the shaped gel to yield carbonaceous MAX phase structures with a composition represented by Mn+1AXn, wherein n is 1, 2, 3, or 4. The MAX phase structures can be thick films, microspheres, or microwires.
    Type: Grant
    Filed: July 21, 2022
    Date of Patent: February 18, 2025
    Assignee: Arizona Board of Regents on behalf of Arizona State University
    Inventors: Christina S. Birkel, Jan P. Siebert
  • SOL-GEL SYNTHESIS OF PHOSPHOROUS-CONTAINING MAX PHASE V2PC
    Publication number: 20240247111
    Abstract: Making a MAX phase material having a composition represented by V2PC includes combining a transition metal component, a phosphorus component, and a carbon component to yield a mixture, heating the mixture to yield a gel, and heating the gel to yield the MAX phase material. wherein the MAX material has a composition represented by V2PC. The transition metal component includes vanadium, the phosphorus component includes phosphoric acid, and the carbon component includes an organic compound. The MAX phase material can be in the form of a film, microsphere, or microwire.
