METHOD FOR PRODUCING DISPLACEMENT PLATING PRECURSOR

摘要

PROBLEM TO BE SOLVED: To provide a method for producing a displacement plating precursor which can form a Cu monatomic layer on the surface of Pt particle or Pt alloy particle without using any external electric source.

SOLUTION: The method for producing a displacement plating precursor comprises a deposition step of depositing the Cu layer on the surface of the core particle by bringing an aqueous acid solution containing Cu ions into contact with at least a part of a Cu electrode, bringing a core particle comprising Pt or a Pt alloy or a composite composed of the core particle carried by an electroconductive carrier into contact with the Cu electrode in the aqueous acid solution or outside the aqueous acid solution, and bringing the core particle into contact with the aqueous acid solution in an inert gas atmosphere.
