Revolutionizing carbon chemistry: Solar ‐powered C(sp3)–N bond activation and CO2 transformation via newly designed SBE‐Y cutting‐edge dynamic photocatalyst

In this paper, we report an artificial photosynthesis system that appears to have had substantial success in terms of 1,4-NADH regeneration, formic acid production from CO2, and fine chemical synthesis. The regenerated 1,4-NADH is then used exclusively in the synthesis of formic acid. Formic acid (HCOOH) is a simple organic acid that might be used as a chemical feedstock. Furthermore, the system is capable of synthesizing fine compounds with a conversion yield of 99.9%. This indicates a high level of efficiency in converting raw materials (perhaps CO2) into useful chemical products. AbstractA solvent-free sulfur-bridge-eosin-Y (SBE-Y) polymeric framework photocatalyst was prepared for the first time through an in  situ thermal polymerization route using elemental sulfur (S8) as a bridge. The addition of a sulfur bridge to the polymeric framework structure resulted in an allowance of the harvesting range of eosin-Y (E-Y) for solar light. This shows that a wider range of solar light can be used by the bridge material's photocatalytic reactions. In this context, supercharged solar spectrum: enhancing light absorption and hole oxidation with sulfur bridges. This suggests that the excited electrons and holes through solar light can contribute to oxidation –reduction reactions more potently. As a result, the photocatalyst-enzyme attached artificial photosynthesis system developed using SBE-Y as a photocatalyst performs exceptionally well, resulting in high 1,4-NADH regeneration ...
