摘要

The increasing concentration of atmospheric carbon dioxide (CO₂) is a major contributor to climate change and global warming, posing serious threats to human welfare. In this work, we report the synthesis of a metal-free, cost-effective, sustainable, reusable, and efficient EY-Ben-S-gC3N4 composite via a co-polymerization strategy, combining co-doped graphitic carbon nitride (Ben-S-gC3N4) with Eosin-Y (EY). Inspired by natural photosynthesis, this artificial photosynthetic system enables the fixation of atmospheric CO₂ into value-added fuels, such as formic acid, achieving a maximum formic acid yield of 204.96 ± 0.5 µM. Additionally, the composite demonstrates the ability to photo-regenerate enzymatically active reduced nicotinamide adenine dinucleotide (NADH) with a conversion efficiency of up to 82.31 ± 0.2%. The system exhibited excellent photostability and recyclability over multiple cycles, maintaining consistent catalytic performance. The concurrent production of formic acid and 1,4-NADH highlights the potential of this system for applications in renewable energy and sustainable chemical synthesis, offering a promising pathway for integrated carbon capture and solar-to-chemical energy conversion.
