| 제목 | Outer-Sphere Electron Transfer Process of Molecular Donor-Acceptor Organic Dye in Dye-Sensitized Photocatalytic System for CO2 Reduction |
| 초록 | Herein we report that porphyrin oligomers (D-ZnPand T-ZnP) derived from M-ZnP can be applied as photosensitizersin photocatalytic systems. Butadiyne-linkedporphyrin oligomer has light-harvesting ability even from low-energy lightsource due to their extended conjugation length. These results support the significantimprovement of the CO2 conversion efficiency in the photocatalyticsystem using the porphyrin oligomer as a photosensitizer. Indeed, thephotocatalytic CO2 conversion efficiency in binary hybrid systemusing Re(I) doped TiO2 is improved when using porphyrin oligomerinstead of M-ZnP. Although the CO2 conversion efficiency ofporphyrin oligomer is relatively lowered than M-ZnP in the homogeneoussystem (Dye + Cat.) due to the lowered electron reduction power and the weakerdriving force of ED (ΔG* = Eox (ED) – Ered*(X-ZnPs)),the radical anion of the porphyrin oligomer, has much higher intensity andlonger lifetime than that of M-ZnP. |
