Postdoctoral Position

Metal-Organic Frameworks for CO2 valorisation

using Frustrated Lewis Pairs

Position for 12 months - Starting date from January 2022

Financial support: Region Ile de France (DIM Respore)

Laboratoire de Chimie des Processus Biologiques (LCPB), Collège de France, Paris, France

The post is available as part of a collaborative research project between LCPB at the Collège de France (Paris), IRCELYON (Lyon) and SOLEIL Synchrotron AILES beamline (Saclay). The objective of the project is to investigate porous hybrid materials with targeted functionalization towards CO2 conversion into small molecules.

Context: The chemical sequestration of CO2 using Frustrated Lewis... Pairs (FLPs) is attracting increasing attention as an efficient strategy for the conversion of CO2 into CO or formate through hydrogenation protocols (Sakakura T, Choi J-C, Yasuda H. Chem Rev 2007, 107:2365). Despite their enormous potential, the practical use of FLPs faces similar limitations than conventional homogeneous catalysts (stability, catalyst/product separation, recyclability) making the proof-of-concept of their transfer to the solid state a currently hot topic, including to Metal-Organic Frameworks (MOFs) (Y. Ma et al. Chem. Soc. Rev. 2018, 47, 5541). In that context, we are currently investigating the functionalization of well-selected MOFs with sufficient pore size to accommodate covalently-grafted FLP and allow fast diffusion for catalysis purposes. These solids all contain suitable organic ligands amenable to the required click-chemistry to synthesize covalently bonded [email protected] These innovative solids are designed as catalysts for the heterogeneous hydrogenation of CO2 within a historical collaboration between the Collège de France and IRCELYON, with the aim to define optimal operating conditions in terms of pressure and temperature, while taking great care to evaluate the selectivity and recyclability of such complex solids.

Recent publications of the team include those on metal-organic frameworks functionalized to perform photocatalytic reactions such as OER (J. Am. Chem. Soc. 2018, 140, 10, 3613-3618; ACS Applied Materials and Interfaces 2019, 11, 51, 47837-47845), HER (Chem. Comm., 2019, 55, 4166) and CO2RR (ChemSusChem 2015, 8, 603-608; ACS Catalysis 2018, 8, 3, 2030-2038; Angew. Chem. Int. Ed. 2020, 59, 5116-5122, J. Am. Chem. Soc. 2020, 142, 20, 9428-9438) or on peptide-functionalized MOF to perform molecular recognition in view of asymmetric catalysis (Chem., Eur. J. 2016, 22, 16531-16538). Our team tends to rely on tight interactions between theoreticians and experimentalists so as to drive the design of functional materials with interesting catalytic properties.

The aim of the post-doc project will be to investigate the catalytic properties of such [email protected] systems for CO2 hydrogenation at the Collège de France setting up liquid phase catalytic tests, having access to a unique well-equipped analytical platform to monitor and quantify the production of CO and methane (gas chromatography coupled to a methanizer), formate, oxalate (ion exchange chromatography coupled to conductimetry), methanol (GC and NMR), formaldehyde (colorimetric tests). In parallel, IR spectroscopy at the synchrotron SOLEIL facilities (first campaign in February 2022 at AILES beamline) will give us access to in situ gas phase conditions (under CO2 and H2 pressure) and will be key in scrutinizing host-guest interactions in the porous [email protected] solids, through the vibrational behavior of CO2 upon targeted conditions of pressure and temperature. IR spectroscopy at AILES will thus be key in investigating in situ CO2 spectral signatures, the intramolecular modes of the actives sites (FLPs) and of the host-matrix (MOF), the reaction intermediate and the final product of the reaction. Due to its high sensitivity towards chemical composition and environment in both gaseous and condensed phases, infrared spectroscopy is one of the most appropriate techniques used in catalysis for in situ monitoring the interaction between molecules and a porous host (H.D. Nguyen et al. ChemSusChem. 2020 DOI: 10.1002/cssc.201902875. J.-B. Brubach et al. J. Am. Chem. Soc. 2016, 138, 33, 10437-10443).

Overall, we aim at demonstrating that the functionalization of well-selected porous solids with rationally designed FLPs will provide novel heterogeneous [email protected] catalysts, exhibiting great potential for developing a novel chemistry for the activation of small inert molecules such as CO2.
