Confining charge-transfer complex in a metal-organic framework for photocatalytic CO2 reduction in water

Abstract In the quest for renewable fuel production, the selective conversion of CO 2 to CH 4 under visible light in water is a leading-edge challenge considering the involvement of kinetically sluggish multiple elementary steps. Herein, 1-pyrenebutyric acid is post-synthetically grafted in a defect-engineered Zr-based metal organic framework by replacing exchangeable formate. Then, methyl viologen is incorporated in the confined space of post-modified MOF to achieve donor-acceptor complex, which acts as an antenna to harvest visible light, and regulates electron transfer to the catalytic center (Zr-oxo cluster) to enable visible-light-driven CO 2 reduction reaction. The proximal presence of the charge…
