| 제목 | Photocatalytic conversion of CO2 into C1 to C2 products |
| 초록 | The photocatalytic conversion of CO2 is a feasible route for reducing atmospheric CO2 concentrations and solar energy storage. We describe highly efficient Pt-sensitized graphene-wrapped defect-induced blue-colored titanium that produces a combined methane and ethane. A systematic ultraviolet photoelectron spectroscopy study on the mechanism underlying ethane formation indicates that the process depends on upward band bending at the reduced blue-titania/graphene interface. We find that mechanisms serve to enhance multielectron transfer processes that generate ˙CH3. Utilizing a continuous flow-through (CO2, H2O) photoreactor throughout multiple 7 h runs, approximate totals of 77 μmol g−1 C2H6 and 259 μmol g−1 CH4 are obtained under one sun AM 1.5G illumination.
