| Research Abstract |
The vitamin B12-TiO2 hybrid catalyst mediated the H2O reduction to form hydrogen under UV light irradiation (1 turnover number per hour). The catalyst also mediated alkene reductions, such as styrene derivatives and alkylacrylates (maximum 100 turnover number per hour), under mild conditions; i.e., room temperature, ordinary pressure, and water or alcohol solvent. We also succeeded in development of visible light responsive vitamin B12-TiO2 hybrid catalytic system using a catechol modified TiO2 which showed surface charge transfer band in the visible region.
