Outline of Final Research Achievements	This proposal aimed to constract a visible light-driven carbon dioxide reduction system by developing a photo/biocatalyst composite system, in which a biocatalyst with catalytic activity for carbon dioxide reduction stabilised by a functional porous material was combined with a photocatalytic material. Professor Kevin C-W. Wu and researcher of our institute were responsible for the design and development of functional porous materials as key materials, aiming to prepare a novel photocatalytic reduction system for carbon dioxide. During the research period, the permission to travel to Taiwan was not granted due to COVID-19, but Prof. Wu visited Japan and the principal investigator visited the site and achieved the development of new electron mediators and colloidal particulate catalysts for the construction of a hybrid carbon dioxide photoreduction system. Finally, the international collaboration resulted in the establishment of the Bule Energy Laboratory at National Taiwan University.

Academic Significance and Societal Importance of the Research Achievements	研究開始当時は台湾では二酸化炭素の利用に関する本格的な研究はまだ進められていなかったが、本国際共同研究を通して、台湾でも二酸化炭素の利用に関する研究が飛躍的に進みだした。加えて、Kevin C-W. Wu教授との共同研究を本格的に進めた結果、国立台湾大学内に共同研究室Bule Energy Laboratoryを設置するに至った。二酸化炭素の利用に関する研究の学術的な意義を国際的に広めたこと、世界的な問題となっている二酸化炭素削減に関して、その解決の糸口を両国で認識し、研究を進めた意義は大きい。
