| Outline of Final Research Achievements |
The B12 complex-titanium oxide (TiO2) composites become an efficient catalyst for light-driven molecular transformations due to the synergistic effect by both components. Novel bioinspired reactions were also developed with the B12-TiO2 hybrid catalyst. The covalently bound B12 on the TiO2 surface transformed the trichlorinated organic compounds into an ester and amide by UV light irradiation under aerobic condition.
Next, we synthesized new B12-TiO2 hybrid catalyst composed of interfacial complexation with catechol. As a charge transfer band ascribed to catechol to TiO2 appears in visible light region, this new hybrid catalyst is expected to work under visible light irradiation.
