  • Graphene-transition metal catalyst for hydrogen evolution reaction
    Patent number: 11969713
    Abstract: Functionalized catalysts for use in a hydrogen evolution reaction (HER) contain nanoparticles containing a transition metal enveloped in layers of graphene, which renders the nanoparticles resistant to passivation while maintaining an optimal ratio of transition metal and transition metal oxide in the nanoparticles. The catalysts can be utilized with anionic exchange polymer membranes for hydrogen production by alkaline water electrolysis.
    Type: Grant
    Filed: December 21, 2020
    Date of Patent: April 30, 2024
    Assignee: Northeastern University
    Inventors: Sanjeev Mukerjee, Robert Allen, Huong Thi Thanh Doan, Ian Kendrick

  • Nitrogen-functionalized platinum-iridium electrocatalyst
    Patent number: 10784518
    Abstract: The invention provides a nitrogen-functionalized platinum-transition metal catalyst having the formula Pt-M-NX/C (where M is a transition element such as Fe, Co, Ni, Nb, Ta, Ir, Rh, or Ru) for use at the hydrogen electrode of a hydrogen/bromine redox flow battery. The new catalyst possesses excellent activity and durability in the HBr/Br2 environment, showing superior resistance to halide poisoning than conventional Pt/C or Pt-M/C catalysts.
