Outline of Final Research Achievements

Dual-functional catalysis is the novel catalysis that induces oxidation under irradiation as well as in the dark. Organic p-n bilayer, comprising p-type and n-type semiconductors, is the promising material capable of dual catalysis. The findings of this study are summarized as follow: it is noted that the dual catalyses were found to occur efficiently when co-catalyst was properly loaded at the organo-bilayer towards oxidation involving multi-electrons transfer.

Academic Significance and Societal Importance of the Research Achievements

酸化チタン光触媒は環境浄化の点で特に効果を発揮し、日本発の技術として広く実用化されている。しかし、光触媒は一般に、光照射下でのみ作用するため、暗所下における対応が課題であった。本研究で取り上げたデュアルキャタリシスは、暗所下でも光照射下と同様に酸化反応を誘起する触媒作用である。このような従来技術には備わっていない触媒作用を、用いる材料や用途も含めて開拓するための研究を行った。
