제목 Molecular Engineering of Donor-Acceptor Organic Dye Sensitizer for Highly Efficient Hybrid CO2 Reduction Catalytic System
초록 Based on the molecular design that introduces a non-planar bulky bis-dimethylfluorenyl amino group and benzothiadiazole moiety as electron donor and electron acceptor unit, respectively, we have finely tailored a metal-free organic dye in photocatalytic CO2 reduction system prepared by fixing a dye and a Re(I) complex on TiO2 nanoparticles. In series of dyes, Flu-CNCA-sensitized TiO2/ReP particles exhibited the most efficient CO2 to CO conversion activity (a TONCO of ~1089 for >70 h) with 3 vol % H2O in DMF solution; irradiation at λ >400 nm. Under irradiation at λ > 500 nm, the hybrid ternary system using π-extended dye showed more than 5 times higher CO2 to CO conversion activity than conventional organic dye.
