Outline of Final Research Achievements

Pt-Au alloy and Pt-shell Au-core core-shell nanoparticles (NPs) show superior durability as the oxygen reduction reaction (ORR) catalysts for polymer electrolyte fuel cell (PEFC). However, the relation between surface atomic ratio and structural stability of the Pt-Au NPs under applying electrochemical potential cycling (PC) has yet to be further elucidated. In this study, Pt-Au NPs are synthesized by using arc-plasma deposition (APD) method onto highly-oriented pyrolytic graphite (HOPG) substrate in ultra-high vacuum. Then, ORR activities and electrochemical structural stabilities of the APD Pt-Au NPs are discussed.
