Outline of Final Research Achievements

In this study, the development of novel visible-light-responsive photocatalysts for water splitting has been performed on the basis of structural designability of porous coordination polymers (PCPs), which is derived from various combinations of their constituent metal-oxo clusters and organic linkers. As a result, a PCP consisting of iron-oxo clusters (Fe-PCP) was found to behave as an effective photocatalyst for oxygen evolution reaction under visible light irradiation whose utilizable wavelength for the reaction was the longest among various PCPs developed so far. Moreover, visible-light-driven water splitting was achieved firstly in the field of PCP-based photocatalysts by constructing a Z-scheme system composed of Fe-PCP and a conventional visible-light-responsive hydrogen evolving photocatalyst connected by reduced graphene oxide as solid electron mediator.
