| Research Abstract |
Atomic design of alloy's outermost surfaces is a key to achieve high activity and stability of cathode electrode catalysts for oxygen reduction reaction in fuel cells. Therefore, precise control of atomic arrangements of electrode material surfaces is indispensable. In this study, we fabricate well-defined surface alloys by using molecular beam epitaxy (MBE) through Pt- and Ni-depositions, respectively, onto Au and Pd single-crystal substrates and evaluate electrochemical properties, particularly oxygen reduction reaction activities, of the model catalysts.
