DEMEANOR

The primary aim of this U.S.–France collaborative research project is to design and develop novel, earth-abundant metal catalysts capable of activating and transforming nitrous oxide (N₂O) and carbon dioxide (CO₂), two potent greenhouse gases, into value-added chemicals such as alcohols, epoxides, and polycarbonates. The project will explore bimetallic coordination strategies to enhance small molecule activation through an integrated approach that combines computational modeling, homogeneous and supported catalysis, and operando spectroscopy. This work aspires to establish sustainable catalytic methodologies that not only mitigate greenhouse gas emissions but also convert them into valuable chemical feedstocks. The collaboration employs complementary expertise across synthesis, catalysis, spectroscopy, and computation, offering unique training opportunities for students and postdocs through joint mentoring and transatlantic research exchanges. The project will provide fundamental insights into how N₂O and CO₂ interact with homogeneous and supported catalysts made from earth-abundant metals. A central hypothesis is that bimetallic coordination will enhance the activation and reactivity of these small molecules. By leveraging expertise in DFT modeling, organic synthesis and homogeneous catalysis, as well as supported catalysis and operando spectroscopy, the project will utilize computational predictions to guide experimental catalyst development. This synergistic, interdisciplinary approach will accelerate the discovery of new catalytic systems and mechanistic pathways for N₂O and CO₂ conversion, addressing key challenges in sustainable chemistry. The expected results will reshape our understanding of small-molecule (N2O and CO2) reactivity and create new opportunities for greenhouse gas valorization through efficient, selective, and energy-conscious chemical transformations.
