| Outline of Final Research Achievements |
The purpose of this study is to reveal the ability of special alloy, intermetallic compound, to be an excellent catalyst. Impregnation procedure with appropriate metal precursors and reductants provided single-phase particles of intermetallic compounds with diameter smaller than 10 nm on various supports. Some compounds between noble metal and typical element showed higher selectivity than pure metal catalysts in selective hydrogenation, oxidative dehydrogenation, etc. The strong correlation was found between catalytic property and the nature of intermetallic compound, such as, surface atomic arrangement and electronic state of surface atoms. It is concluded that intermetallic compounds are promising materials to obtain high-performance catalysts.
