Research interests

Research interests are focused on the preparation of transition metal substituted PolyOxoMetalates or covalently functionalized POMs as catalysts for atom or group transfer reactions with an emphasis on catalytic oxidation with low environmental impact.

  • (Photo)catalysed (ep)oxidation reactions of alkanes and alkenes
  • Functional models of isolated sites for heterogeneous catalysts
  • Amphiphilic POMs as catalytic surfactants

Keywords: polyoxometalates, inorganic-organic hybrids, early-transition metals, site-isolated catalysts, homogeneous and biphasic catalysis, oxidation.

Selected recent results

  • Silanol-decorated PolyoxoMetallates (SiloxPOMs) : Site isolated models for vanadium-oxides active in oxidation reactions (ACS Catal. 2015 ; J.Am.Chem.Soc. 2018, Inorg. Chem. 2022)
  • Titanium-SiloxPOMs : mechanistic investigations on Alkene epoxidation by molecular analogues of heterogeneous Titanium-Silicalite Catalysts (ACS Catal. 2018 ; ACS Catal. 2020, ChemCatChem 2021)
  • Preparation of amphiphilic POMs (AMPHI-POMs) : towards the design of oxidizing polyphasic microdispersed reaction media (Chem. Commun. 2014, Chem. Soc. Rev. 2022)

  • Habilitation thesis, Sorbonne Université, 2019.
  • PhD in Chemistry, Ecole Polytechnique Fédérale de Lausanne, 2002.
  • Undergraduate studies at UPMC, Paris and Ecole Polytechnique, Palaiseau
