  • Metal fine particle association and method for producing the same
    Patent number: 9893366
    Abstract: There is provided a metal fine particle association suitably applied to an electrode catalyst to achieve even higher output leading to reduction in amount of the catalyst used, and a process for producing the same, that is, a metal fine particle association including a plurality of metal fine particles that have a mean particle diameter of 1 nm to 10 nm and are associated to form a single assembly, an association mixture including the metal fine particle association and a conductive support; a premix for forming an association, including metal fine particles, a metal fine particle dispersant made of a hyperbranched polymer, and a conductive support; and a method for producing the association mixture.
    Type: Grant
