An inorganic chemist by training, I have developed expertise in the development of composite nanomaterials for catalytic applications, mainly based on metals, oxides and carbons. This expertise includes the design of tailor-made chemical syntheses, the in-depth characterization of the obtained composites, in terms of composition, size, interfacing and interaction between the different components, and the study of the catalytic reaction (reaction mechanisms). The formulation of the materials is rationally optimized on the basis of correlations between structural configuration and catalytic properties. Involved in the fields of environment and energy, I have focused my research on the development of more selective and sustainable catalysts, in particular based on gold nanoparticles.

I am currently developing plasmonic catalysts for artificial methane photosynthesis. I am seeking to understand the mechanisms of this reaction, in collaboration with researchers from the Fresnel Institute, the LPCNO and the LCC. I am evaluating the potential and specificities of plasmon-induced catalysis, resulting from the confinement of light in metal nanoparticles.
