- W4385514984 abstract "Abstract Photocatalytic hydrogen production via water splitting is the subject of intense research. Photoinduced electron transfer (PET) between a photosensitizer (PS) and a proton reduction catalyst is a prerequisite step and crucial to affecting hydrogen production efficiency. Herein, three photoactive metal–organic framework (MOF) systems having two different PET processes where PS and Co(II) centers are either covalently bonded or coexisting to drive photocatalytic H 2 production are built. Compared to these two intramolecular PET systems including Co II ‐Zn‐PDTP prepared from the post‐synthetic metalation toward uncoordinated pyridine N sites of Zn‐PDTP and sole cobalt‐based MOF Co‐PDTP, the Co II (bpy) 3 @Zn‐PDTP system impregnated by molecular cocatalyst possessing intermolecular PET process achieves the highest H 2 evolution rate of 116.8 mmol g −1 h −1 over a period of 10 h, about 7.5 and 9.3 times compared to Co II ‐Zn‐PDTP and Co‐PDTP in visible‐light‐driven H 2 evolution, respectively. Further studies reveal that the enhanced photoactivity in Co II (bpy) 3 @Zn‐PDTP can be ascribed to the high charge‐separation efficiency of Zn‐PDTP and the synergistic intermolecular interaction between Zn‐PDTP and cobalt complexes. The present work demonstrates that the rational design of PET process between MOFs and catalytic metal sites can be a viable strategy for the development of highly efficient photocatalysts with enhanced photocatalytic activities." @default.
