Outline of Final Research Achievements

We have developed a novel catalytic space composed of copper metal surface and organic network structure. The cooperation of two materials are achieved by on-surface preparation of insoluble organic network by electrochemically activated metallic copper. The reduction of carbon dioxide on the modified electrode shows improvement of CO2 selectivity, contrary to the modification with traditional cast method. The selectivity in methane/ethylene formation can be biased with the kind of introduced organic structure. These results demonstrates the placement, and the selection of organic structure can be applied for the design of surface catalytic process, just as seen in molecular coordination catalyst.

Academic Significance and Societal Importance of the Research Achievements

金属はこれまで広く触媒として用いられ、ナノ粒子などの発展が著しい。また錯体触媒のように、単一の金属原子あるいはイオンを有機物構造に精密に取り込むことで、高活性、あるいは選択性の高い反応空間を構築するという方法も非常に成功を収めている。しかし、構造に柔軟性の高い金属表面と有機物の組み合わせによって反応空間を構築する方法はまだ未発展の分野である。本研究の成果は、有機物と金属表面を近接するが吸着しないストレスのある反応場を構築すれば高活性を発現しうること、また多様性とともに精密設計の可能な有機物を選択して金属表面に配置することでその触媒活性をチューニングできることを示している。
