Highly Selective Nitrogen-Doped Graphene Quantum Dots/Eriochrome Cyanine Composite Photocatalyst for NADH Regeneration and Coupling of Benzylamine in Aerobic Condition under Solar Light

Photocatalysis is an ecofriendly and sustainable pathway for utilizing solar energy to convert organic molecules. In this context, using light responsive graphene-based materials C–N bond activation coenzyme regeneration (nicotinamide adenine dinucleotide hydrogen; NADH) one of the utmost important challenging tasks in century. Herein, we report synthesis nitrogen-doped graphene quantum dots (NGQDs)-eriochrome cyanine (EC) active highly efficient “NGQDs@EC” composite photocatalyst conversion 4-chloro benzylamine into benzylamine, accompanied by NADH from NAD+, respectively. The NGQDs@EC system utilized a stereospecific manner, leading imine (98.5%) (55%) comparison NGQDs. present research work highlights improvements use under light.
