Abstract
Physico-chemical methods are used to show that Pt-Ni particles obtaine d by the simultaneous reduction of the salts Pt2+ and Ni2+ by sodium n itrate have a mean diameter of about 2 nm. It is determined that nicke l and platinum do not form an alloy and that the particles have the st ructure of a sweet cherry, consisting of a platinum stone and a nickel pulp. Both the nickel and the platinum are in the oxidized state in t his case.
