New Strategies to Capture and Use CO2 as a Sustainable Carbon Source in the Synthesis of Value-Added Compounds

This work focuses on the development of sustainable strategies for carbon capture and utilization (CCU), a key technology for mitigating global warming by using CO₂ as a renewable carbon source.

Here we explored the role of quaternary ammonium salts in enhancing CO₂ capture and activation with NaBH₄. The presence of these salts resulted in both shorter reaction times and improved efficiency.

The synthesis of N-arylureas from urea was also investigated, demonstrating that deep eutectic solvents (DES) not only serve as sustainable reaction media but also significantly promote the reaction, resulting in substantially improved yields.
