PLATINUM SKELETON ALLOY-SUPPORTED ELECTROCATALYST, ELECTRODE USING THE ELECTROCATALYST, AND PROCESS FOR PRODUCING THE ELECTROCATALYST

摘要

An electrocatalyst comprising an alloy of platinumwith a base metal selected from the group consisting ofgallium, vanadium, chromium, manganese, iron, cobalt,nickel and copper, having a structure of vacant lattice sitetype lattice defects; the alloy being supportedon a conductive carbon powder. The electrocatalyst isuseful as a platinum-supported catalyst for anelectrode, and has a superior electrochemical oxygenreduction activity and has platinum alloy particles havingless base metal component.
