Outline of Final Research Achievements |
In this project, we investigated correlation between the catalytic properties and the metal-metal mutual interaction (e.g., solid solutions, intermetallic compounds and immiscible) in terms of metallurgy. We demonstrated that the formation of alternately layered structure, e.g., Al5Fe2/Al2Pt/Al5Fe2, with an interspacing about ~200 nm in a conventionally solidified alloy (e.g., Al-Pt-Fe alloy). Alloys solidify through a so-called eutectic reaction normally show the interspacing around 10μm, but that appeared in the Al-Pt-Fe is almost smaller by two order. The catalyst improved the catalytic performance and/or created a novel catalytic function, depending on the combination of metals. We developed a fine alternately layered nanoporous composite and a novel alloy with useful for catalysis materials.
