Outline of Final Research Achievements

Transient changes in the structural and electronic states of photoreactive proteins and many homogeneous and heterogeneous photocatalysts were visualized by X-ray molecular imaging and theoritical approaches, and the dynamic information provided design guidelines for synthesizing more efficient photocatalytic materials. Pump-probe measurements using XFEL and operando measurements using synchrotron radiation enabled us to visualize the initial reaction pathway and the progress of the reaction diagram. This artificial photosynthesis study presented a new approach to detail the factors that determine the efficiency and selectivity of photofunctionality from a structural and electronic point of view.

Academic Significance and Societal Importance of the Research Achievements

高機能な光触媒材料の反応過程を追跡することで、それを模倣して更に良い機能性を持たせるには、素過程としてどのような電子状態・構造を持てばいいのか、このような基本的かつ根本的な問題に対して、構造・局所電子状態の立場から指標を与えられた点に、本研究の学術的意義がある。また、他の計測技術と相補的な比較研究ができ、また、材料開発研究とも密接な連携が行える本研究は、エネルギー問題解決に向けた人工光合成研究の活性化をもたらす点において、大きな社会的意義を持つ。
