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

Abstract

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.
