Highly efficient solar to chemical conversion by 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 charge carrier lifetime of photocatalyst, leading to a doubled H2O2 yield via dual reaction pathways. Subsequent enzymatic epoxidation achieves a 2.26-fold higher yield compare with free enzyme, demonstrating efficient solar-to-chemical conversion
