- 摘要：
- Upcycling carbon dioxide (CO2) into long-chaincompounds has attracted considerable attention with respect tomitigating environmental problems and obtaining value-addedfeedstocks, but remains a great challenge. Herein, we report atandem photocatalysis-biosynthesis strategy for efficient CO2reduction to energy-rich sucrose or -farnesene. Firstly,photocatalytic reduction of CO2 to CH4 was optimized over thetransitional metal doped ZnO (M-ZnO). The as-prepared Ni-ZnOpreferentially reduces CO2 to CH4 with a production rate of 1539.1µmol g−1 h−1 and a selectivity of 90%, owing to the unique interfacestructure (Znδ+−O−Ni+). Subsequently, Methylomicrobiumburyatense 5GB1C was genetically engineered to produce sucroseor -farnesene using photocatalytically-obtained CH4 as the solecarbon source, with a titer of 96.3 and 43.9 mg L−1, respectively. Thisstudy provides a green, low-energy pathway for the synthesis oflong-chain compounds from CO2 as the carbon source, which shedsnew light on tackling long-term energy demands and sustainableCO2 upcycling.
