Chiral compounds are successfully photosynthesized by coupling redox biocatalysis with the photoregeneration of nicotinamide cofactors on quantum‐dot‐sensitized TiO 2 nanotubes under visible light irradiation. Nanotubular morphology and hybridization of TiO 2 with CdS enables highly efficient photoregeneration of cofactors by ensuring better diffusion of reaction species and rapid charge separation.
