  • Methods for producing silver-amended carbon materials
    Patent number: 11974875
    Abstract: Silver-amended carbon materials containing silver nanoparticles are prepared by a process involving an initial reduction of a porous carbon material, followed by contacting the reduced porous carbon material with an aqueous solution of a silver salt. Such silver-amended carbon materials may contain a relatively high loading of silver nanoparticles on both the outside surface and within the interior of the porous carbon material and are useful for disinfecting and/or otherwise purifying fluids such as microbe-containing fluids.
    Type: Grant
    Filed: July 12, 2019
    Date of Patent: May 7, 2024
    Assignee: University of Delaware
    Inventors: Pei-Chun Chiu, Danhui Xin, Steven Lobo, II
