Direct conversion of atmospheric CO2 by homogeneous catalysis

Abstract

With the gradual decarbonization of our economy, only a few isolated sources of CO2 emissions, such as cement plants, will remain. However, our long-term dependence on carbon-based products, such as fuels for aviation and heavy transport, as well as various chemicals and polymers, will persist. To produce these essential molecules, it will be crucial to capture carbon in the form of diluted CO2 from the atmosphere and transform it into useful molecules.

Currently, technologies for the direct capture of CO2 from the air (DAC) are being developed separately from those for CO2 conversion, although their integration could offer significant energy savings, notably by avoiding the energy-intensive thermal desorption stage. The major scientific challenge lies in the development of innovative CO2 conversion methods capable of operating with extremely low CO2 concentrations and/or transforming CO2 directly into its capture medium; for example, in low-reactivity forms such as carbonates or carbamates. The project aims to develop molecular catalysts capable of converting CO2 in very dilute environments, thus producing sustainable molecules and fuels.
