研究の背景 Background


Catalysts play a central role in present industrial production and are key materials in the environment and energy related fields. Recently, replacing noble metals such as Pt and Pd in heterogeneous catalysts by low-cost substitutes has become more and more important in scientific and industrial researches, and an interdisciplinary research between catalysis and metallurgy is strongly desired. However, very few researches on catalytic materials have been performed from the view point of metallurgy so far.

研究の目標 Outcome


In this study, we have fabricated novel catalysis materials from well-defined materials such as intermetallic compounds and spinel oxides etc. These well-defined materials are promising precursors for leaching or reduction for the fabrication of selfassembled nanoarchitecture and for obtaining porous catalysis materials. Novel catalytic materials with high catalytic performance are designed from microstructural tailoring based on metallurgy
