Outline of Final Research Achievements

The purpose of this study was to synthesize metal complexes that mimic the first coordination sphere around the active center of metalloenzymes involved in material and energy conversion in biological systems, and to construct bio-mimetic metal complexes that introduce a multiple-interaction reaction field as a second coordination sphere to induce or stabilize substrates. Specifically, we confirmed the following studies; (1) the confirmation of oxygen activation state of Co complexes, (2) synthesis of V complexes containing V present in nitrogenase and its nitrogen fixation, (3) conversion of CO2 to ethylene, ethanol, and other useful substances using Cu electrodes, (4) development of catalysts for hydrogen production using Ni complexes, and (5) development of several types of ionic liquid-modified electrodes and support of catalysts in them.

Academic Significance and Societal Importance of the Research Achievements

コバルト錯体による酸素活性化の機構、窒素固定化におけるバナジウムの役割、銅電極による炭酸ガス固定の機構、ニッケル錯体による水素生成の機構解明、イオン液体修飾電極の創製と触媒反応への応用が遂行できた。これらの知見、特に反応機構の解明は触媒開発の基盤となるものであり、インパクトファクターの高い幾つかの論文として報告し、学術的意義は大きく、またそれらの触媒開発へも大きく貢献すると考えられ、社会的意義は多大であると考えている。
