Hybrid C3N4/Fluorine‐Doped Tin Oxide Electrode Transfers Hydride for 1,4‐NADH Cofactor Regeneration

Abstract Herein, we report the use of graphitic carbon nitride (C 3 N 4 )‐modified fluorine‐doped tin oxide electrodes for the electroregeneration of reduced nicotinamide adenine dinucleotide phosphate (NADH). We synthesized and functionalized these hybrid electrodes by using anodic aluminum‐oxide‐templated C 3 N 4 growth. Electrochemical activation of the semiconducting C 3 N 4 islands with a rhodium complex permits selective regeneration of biologically active 1,4‐NADH cofactor.
