Pt–Au core/shell nanorods: preparation and applications as electrocatalysts for fuel cells

Abstract

Carbon-supported Pt–Au nanorods with a core/shell structure and excellent oxygen reduction (ORR) activities have been prepared. The Pt shell nanorods exhibit high CO oxidation activity, while the PtAu shell nanorods benefits formic acid oxidation (FAO). The 1-D morphology of the nanorods enhances the electrochemical activity of ORR, FAO and CO oxidation.
