Cadmium sulfide net framework nanoparticles for photo-catalyzed cell redox.


ABSTRACT: A strategy for synthesizing cadmium sulfide net framework (CdS-NF) nanoparticles was developed in a water-based system under mild reaction conditions. The CdS-NFs have not only the excellent photocatalytic properties of CdS, but also the large surface area and diverse porous structures of a metal-organic framework. An Escherichia coli-CdS-NF hybrid system was constructed using NADH regeneration to promote the conversion of trimethylpyruvate acid to l-tert-leucine. The E. coli-CdS-NF system showed higher NAD+ recycling efficiency and substrate conversion rate than CdS QDs under visible light illumination. This work demonstrates a novel method for developing a brilliant coenzyme recycling photocatalyst in bio-redox reactions.
