In this study, a system of photocatalysis for NAD+ regeneration of enzymatic catalysis was constructed. The optimal conditions for the coupling reaction of photocatalysis and biocatalysis were explored. Blue light was chosen for the efficient reaction and the optimal concentration of VB2 (vitamin B2, riboflavin) was determined. NAD+-dependent (R)-1-phenylethanol dehydrogenase was used in the reaction for transforming (R)-1-phenylethanol to acetophenone. The byproducts of the reaction were just
