摘要

Inspired by nature,improving photosensitization represents a vital direction for the development of artificial photosynthesis.The sensitization ability ofphotosensitizers (PSs) reflects in their electron-transfer ability,which highly depends on their excited-state lifetime and redox potential.Herein,for the first time,we put forward a facile strategy to improve sensitizing ability via finely tuning the excited state of Ru(Ⅱ)-PSs (Ru-l-Ru-4) for efficient CO2 reduction.Remarkably,[Ru(Phen)2(3-pyrenylPhen)]2+ (Ru-3) exhibits the best sensitizing ability among Ru-1-Ru-4,over 17 times higher than that of typical Ru(Phen)32+.It can efficiently sensitize a dinuclear cobalt catalyst for CO2-to-CO conversion with a maximum turnover number of 66 480.Systematic investigations demonstrate that its long-lived excited state and suitable redox driving force greatly contributed to this superior sensitizing ability.This work provides a new insight into dramatically boosting photocatalytic CO2 reduction via improving photosensitization.
