  • LABORATOIRE CATALYSE & SPECTROCHIMIE

    The Catalysis and Spectrochemistry Laboratory (LCS) works on the preparation and study of solid catalysts for applications in environment and sustainable development. LCS is leader in the observation of catalytic materials inside a working reactor, in real time, during the chemical reaction (operando spectroscopy). With its very strong facility in infrared spectroscopy, and with some NMR, Raman and Uv-vis spectroscopies, LCS is in a unique position in car exhaust treatment, pollution abatement, in energy production (oil refining, bio-fuels) and in the domain of bio-sourcing of chemistry.
