Abstract Upcycling carbon dioxide (CO 2 ) into long‐chain compounds has attracted considerable attention with respect to mitigating environmental problems and obtaining value‐added feedstocks, but remains a great challenge. Herein, we report tandem photocatalysis‐biosynthesis strategy for efficient CO reduction energy‐rich sucrose or α‐farnesene. Firstly, photocatalytic of CH 4 was optimized over the transitional metal doped ZnO (M−ZnO). The as‐prepared Ni−ZnO preferentially reduces production rate 1539.1 μmol g −1 h selectivity 90 %, owing unique interface structure (Zn δ + −O−Ni β ). Subsequently, Methylomicrobium buryatense 5GB1C genetically engineered produce α‐farnesene using photocatalytically‐obtained as sole source, titer 96.3 43.9 mg L , respectively. This study provides green, low‐energy pathway synthesis from which sheds new light on tackling long‐term energy demands sustainable upcycling.

Lead-based halide perovskites (LHPs) have been widely explored by researchers in the field of photocatalysis. However, poor stability and toxicity LHPs limit their large-scale applications. Here, lead-free Cs2AgBiBr6/BiVO4 (CABB/BVO)-X% (X = 30, 50, 100) S-scheme heterojunction composites are prepared electrostatic assembly, catalytic activity for photoreduction CO2 is evaluated. After 3 h simulated solar irradiation, CABB/BVO-50% show highest CO yield electron consumption rate 143.59 352.22 µmol g-1, which 9.2 7.8 times higher than that CABB alone, respectively. In addition, photocatalysts exhibit 81.5% high selectivity CO. The generation an internal electric (IEF) between two materials heterojunctions powerfully confirmed employing various characterization techniques DFT calculations. low carrier recombination rate, bandgap-matched heterointerfaces, exceptional charge transfer mechanism primarily responsible outstanding performance. This work provides new insights into design efficient perovskites-based photocatalytic materials.
