ABSTRACT:
An electrocatalyst comprising an alloy of platinum with a base metal selected from the group consisting of gallium, vanadium, chromium, manganese, iron, cobalt, nickel and copper, having a structure of vacant lattice site type lattice defects; the alloy being supported on a conductive carbon powder. The electrocatalyst is useful as a platinum-supported catalyst for an electrode, and has a superior electrochemical oxygen reduction activity and has platinum alloy particles having less base metal component.
