This experimental postdoc offers an opportunity to contribute to the pluridisciplinary project CO2KARMA aiming to characterize and understand a CO2 activation process in heterogeneous catalysis. More specifically, the recruited postdoctoral research assistant (PDRA) will identify the sites active in catalysis of DMC synthesis. The PDRA will synthesize a set of model catalysts and develop a strategy based on quantitative correlations between structural parameters, thermodynamic and spectroscopic properties, and catalytic performances. She/he will thus take advantage of our expertise in synthesis, catalysis and spectroscopy (PhD thesis defended in September 2017, publication on-line) and she/he will discuss her/his results together with those obtained in quantum modeling by the first PDRA working on the CO2KARMA project (current contract).
The recruited PDRA will synthesize the metal oxides selected for their performances in catalysis of AN on CO2, using protocol already developed for the project. He/she will characterize the surface sites with adsorption and spectroscopic experiments (FTIR, 1H and 17O NMR), in MACS lab and on the University Montpellier platform for analysis and characterization, in collaboration with the consortium experts (H. Petitjean and A. Travert for the FTIR spectroscopy and D. Laurencin for the NMR). The PDRA will also travel on mission to Caen in LCS to do advanced experiments in FTIR spectroscopy coupled with gravimetry. Along with the characterization work, he/she will determine the catalytic reactivity of the same catalysts with model reactions (methylbutynol conversion and DMC synthesis), in collaboration with N. Tanchoux and D. Tichit. The PDRA will look for structure-properties relationships to improve the assignments of the experimental spectra and to extract the structural parameters ruling the reactivity. Within the project CO2KARMA, the PDRA will develop her/his expertise in characterization and understanding of oxide catalysts.
- Literature review and monitoring
- Synthesis of metal oxide catalysts via precipitation or sol-gel methods.
- Classical post-synthesis characterization of catalysts (powder XRD, physisorption, TGA).
- Advanced spectroscopic characterizations : solid state NMR and in situ FTIR.
- Evaluation of performances in heterogenous catalysis : in gas flow with an automated reactor, in liquid phase with batch reactos.
- Result analysis
- Publication writing
- Communications in scientific conferences
PhD in Chemistry of Materials or Heterogeneous Catalysis, motivated with a project involving synthesis and characterization and aiming at understanding the reactivity at the molecular scale.
She/he will have a good knowledge in NMR and FTIR spectroscopy, in surface reactivity (adsorption, heterogeneous catalysis) and in synthesis of solids.
She/he will have a research experience in solid material characterization and in synthesis of materials in solution.
The recruited researcher will be supervised by Hugo Petitjean (permanent CNRS researcher) at the Institut Charles Gerhardt Montpellier, in the team Advanced Materials for Catalysis and Health (MACS).
All the techniques involved in the project are available in the team building (synthesis, catalysis, classical characterizations of catalysts, in situ FTIR) or at the University Montpellier (solid state NMR)
The recruited researcher will also be supervised by the project members who are expert in catalyst synthesis and catalysis (N. Tanchoux and D. Tichit), in in-situ FTIR (H. Petitjean and A. Travert) and in solid state NMR (D. Laurencin). He/she will work in collaboration with a technical staff (J. Rodriguez) for the in-situ FTIR.
Constraints and risks
The researcher will travel on mission to Caen in LCS to do advanced experiments in FTIR spectroscopy coupled with gravimetry.
