    摘要： Disclosed herein is an electrocatalyst comprising a support and active catalyst metal particles supported thereon in which an average interparticle distance of the metal particles is at least 15 nm.
    The overlapping of the territories around the particles between the adjacent particles diminishes thereby so that the desired activity value can be obtained without the decrease of the specific activity even when the particle diameter of the catalyst particles is considerably decreased.

    摘要： A platinum alloy catalyst and a process of preparing the same are disclosed. The platinum alloy catalyst comprising a carbon support and (a) platinum, (b) manganese and (c) at least one of nickel and cobalt supported on the carbon support. The activity of this alloy catalyst is higher that that of conventional catalysts and possesses a longer life. The above process is characterized by use of an organic acid amine salt of manganese, nickel and/or cobalt. The alloying of these metals with the platinum can be carried out at a lower temperature so that the catalyst having a larger surface area can be obtained.

    摘要： Disclosed are a platinum-gold alloy catalyst having a high surface area and a high activity and a process of preparing the same. Gold is effective in depressing the element dissolution of the alloy so that the platinum alloy catalyst containing the gold possesses a high catalytic activity. The platinum alloy catalyst may further contain at least two metals selected from the group consisting of nickel, cobalt and manganese.
