Outline of Final Research Achievements

We investigated the following agendas: a) highly difficult selective conversion of substances, b) utilization of natural energy (light/heat) and waste, and c) visiblization of photocatalyst. We achieved the results shown below. 1) Various photocatalytic reactions proceed under metal-free and hydrogen-free conditions. 2) By introducing a co-catalyst, the reaction rate is significantly increased. 3) Various solvents including water can be used. 4) Under solar irradiation, the reaction proceeds even under passive conditions where no external energy is applied. 5) Waste can be used as a hydrogen source. 6) The reaction rate is greatly increased by elevating the reaction temperature by 30 K.

Academic Significance and Societal Importance of the Research Achievements

自然エネルギーと光触媒を組み合わせることにより、温和な条件において様々な高難度物質変換反応が可能であることを明らかにした。また、その処理にエネルギーを投入している廃棄物を目的反応の水素源に利用できることもわかった。本研究は、自然エネルギーを主な駆動源とする低エネルギー消費型化学工場への道程の第一歩となる。
