Coupling plasmonic catalysis and nanocrystal growth through cyclic regeneration of NADH

In a typical colloidal synthesis, the molecules of the reducing agent are irreversibly oxidized during nanocrystal growth. Such a scenario is of questionable sustainability when confronted with naturally occurring processes in which reducing agent molecules are cyclically regenerated. Here we show that cofactor molecules once consumed in the nucleation and growth of metallic nanocrystals can be photoregenerated using metallic nanocrystals as photocatalysts and reused in the subsequent nucleation process. Cyclic regeneration of cofactor molecules opens up the possibilities for the sustainable synthesis of inorganic nanoparticles.

Automated summary

In the process of synthesizing inorganic nanoparticles, metallic nanocrystals can be utilized as photocatalysts to regenerate cofactor molecules, enabling their cyclic regeneration and reuse in the nucleation process, opening up new possibilities for the sustainable synthesis of inorganic nanoparticles.
