Photocatalytic regeneration of NADH using diatom-inspired chemistry

26-Mar-2013 - Germany

Researchers studying the photocatalytic regeneration of NADH, and its possible application to solar energy conversion, have drawn inspiration from frustule – the silica material that surrounds diatoms. Diatoms are unicellular photosynthetic algae that are known to be highly efficient when it comes to converting light to energy.

In this paper, the authors have constructed a carbon nitride material, with a frustule structure, as part of a highly efficient artificial photocatalytic system that imitates the function of Photosystem I. The system regenerates 1,4-NADH from NAD+, operating with virtually 100% efficiency when [Cp*Ru(bpy)(H2O)] is used as an electron mediator.
