This technology uses functionalized cyclopropenimine (CPI) superbase molecules to efficiently and rapidly capture and upcycle atmospheric carbon dioxide gas into other organic compounds.
Current molecules used industrially in both direct air capture and point-source capture of carbon dioxide (CO2) are generally limited to aqueous amines. However, conventional amines for CO2 capture have low capture capacities, high degradation rates, and require high temperatures and large amounts of energy, so it can take years to convert concentrated CO2 into solid materials. Although amines can be readily produced and used in existing infrastructure, their use is limited in certain carbon capture applications.
This CO2 capture system utilizes cyclopropenimines (CPIs) to efficiently and rapidly capture CO2 in both aqueous and organic solvents. CPIs can be easily prepared from commercially available materials within three steps. Their structural properties allow for CO2 capture and conversion into other organic compounds within minutes at room temperature and pressure. Their properties can be modulated by adding various functional groups to alter CO2 solubility and affinity to allow for upcycling, controlled uptake and release, and mineralization of CO2.
