Outline of Final Research Achievements

Selective hydrogenation of carboxylic acids is an important reaction for the synthesis of alcohols, which are useful chemicals, and it is also highly important from the academic viewpoint because of the low reactivity of carboxylic groups among carbonyl groups and the difficulty of the hydrogenation. In this study, we developed heterogeneous catalysts for the hydrogenation of carboxylic acids by using inexpensive metals as the main active species, and found that Mo-Pt alloy was effective for the reaction at a low temperature of 373 K. Furthermore, we also found that combination of ruthenium metal and Fe iron species showed highly activity and high selectivity to the target alcohols.

Academic Significance and Societal Importance of the Research Achievements

カルボン酸の水素化は、カルボキシ基の反応性の低さから高活性触媒の開発は難しく、また、高価な貴金属が主に使われてきた。本研究では安価な金属を含むMo-Pt合金やFeOxとルテニウムからなるRu-FeOxがカルボン酸の水素化に高活性であることを見出した。このようなMo-Pt合金やRu-FeOx触媒は、白金、ルテニウム、モリブデンや鉄のみでは発現させることができない新しい触媒機能であり、他の還元反応などへの応用展開が期待される。
