  • Nanomaterial preparation method
    Patent number: 11939220
    Abstract: Described is a method of preparing transition metal nanoparticles on a graphene support, in which a tertiary graphite intercalation compound is provided with intercalated metal ions such that the tertiary graphite intercalation compound comprises a graphene sheet having a negative charge. The graphene sheet is contacted with a transition metal salt to cause reduction of the transition metal salt by the graphene sheet, and to form transition metal nanoparticles. Also described are products arising from the method, and uses of those products.
    Type: Grant
    Filed: February 13, 2019
    Date of Patent: March 26, 2024
    Assignee: UCL BUSINESS LTD
    Inventors: Chris Howard, Rhodri Jervis, Daniel Brett, Gyen Angel, Patrick Cullen, Chris Gibbs
