  • Process for producing alloy nanoparticles
    Patent number: 11814737
    Abstract: The present invention relates to a process for the production of metal alloy nanoparticles which catalyse the oxygen reduction reaction (ORR) for use in proton exchange membrane fuel cells (PEMFC) or electrolyser cells. In particular, the present invention relates to a process for producing alloy nanoparticles from platinum group metals and other metals under reductive conditions. In particular the present invention relates to a process for producing alloy nanoparticles comprising the steps of mixing a salt of at least one metal, a material comprising a platinum group metal, a nitrogen-rich compound, and optionally a support material, to provide a precursor mixture, and heating said precursor mixture to a temperature of at least 400° C., in the presence of a gas comprising hydrogen (H2), to provide said alloy nanoparticles.
    Type: Grant
