Highly efficient solar to chemical conversion by an anthraquinone and Candida antarctica lipase B-based photocatalytic-enzymatic cascade.

Herein, we construct a spatially coupled photo-enzymatic cascade system within a ZIF-8 framework. The host-guest interaction narrows the bandgap and prolongs the charge carrier lifetime of the photocatalysts, leading to a doubled H2O2 yield via dual reaction pathways. Subsequent enzymatic epoxidation achieves a 2.26-fold higher yield compared with that of the free enzyme, demonstrating efficient solar-to-chemical conversion.
