Global warming is an issue of increasing concern. The greenhouse effect is a necessary process to maintain living conditions on Earth, but in today’s society, increasing emissions of greenhouse gases into the atmosphere are increasing temperatures by retaining more heat than necessary. .Nature is trying to counteract this situation: plants can capture energy from sunlight and convert CO2 to chemical energy and organic matter.

inspired by this natural processThe Supramolecular and Sustainable Chemistry Group of the Department of Inorganic and Organic Chemistry at the Jaume I University of Castello has developed a catalyst capable of converting CO.2 To high value-added chemical products centered on cyclic carbonates. Validated at an experimental level in a laboratory environment, the technology seeks development and adaptation in specific applications through specific agreements and licenses with companies.

This invention consists of the fields of synthetic chemistry and environmental chemistry, carbon dioxide (CO2) content and fine chemical or pharmaceutical sector industries using chiral cyclic carbonates as intermediates.New pseudopeptide catalytic system can generate cyclic carbonates from dilute CO2 In an enantioselective manner under mild pressure and temperature conditions.

Therefore, this catalyst can contribute to the development of a circular and sustainable economy, where waste or residue from one industry becomes feedstock for another. This technology enables the production of high value-added products such as cyclic carbonates, eco-friendly solvents, lithium ion batterypaints and coatings, resins, precursors of polymeric materials, and polymer processing in fine chemistry.

Some of their technical advantages are the fact that these chiral bimetallic catalysts do not require the presence of a co-catalyst. They can act under moderate pressure and temperature conditions and may be biodegradable due to their pseudopeptide structure. These properties allow Cost reductionreducing the waste generated in catalytic reactions and reusing surplus energy (circular economy) can yield chiral products with high added value.

My work was published in a magazine chemical catalyst.
