Solar light-driven photocatalyst-enzyme attached artificial photosynthetic system for regeneration and production of 1,4-NADH and L-glutamate

In artificial photosynthesis process the photocatalyst-enzyme attached system is a best strategy to utilize solar energy for solar chemical/fuels production. Herein, we prepared a solar light active graphene-based photocatalyst received by the covalent attachment of 9-aminoanthracene (AA) chromophore with chemically converted graphene (CCG) for highly efficient 1,4-NADH regeneration (79.9 %) and conversion of α-ketoglutarate (α-KG) in to Lglutamate (L-GM) (88.3 %) in 2 hrs. The present result is a benchmark example of highly selective solar light active enzyme based artificial photosynthetic system for selective formation of L-GM from α-KG. |
