Outline of Final Research Achievements

Molecular behaviors of several molecules, e.g., energy carrier molecules, organic hydrides, alcohol, carbon dioxide on electrode surfaces are important subjects for future energy systems and, therefore, developments of effective electro-catalysts with suitable surface atomic arrangements and compositions are required. In this study, well-defined model catalysts (X/M(hkl)) are fabricated through molecular beam epitaxy (MBE) of alloying elements X on the low-index single crystal surfaces of Pt and Au (M(hkl); M=Pt, Au)). Then, surface structural analysis, electrochemical measurements are performed for the prepared X/M(hkl) model catalysts and discussed the relation between surface atomic arrangements, alloy compositions and catalytic properties.
