The Catalysis and Spectrochemistry Laboratory (LCS) has built its reputation on operando spectroscopy of the catalyst, that is to say on the observation of the material in the chemical reactor, in real time, during the reaction. Since 2009, the LCS has also been recognized worldwide for its research into the design of microporous materials, such as zeolites, with specific properties. With a very strong pole in infrared spectroscopy, but also in NMR and Raman spectroscopy, the LCS occupies a unique place in the field of automotive depollution, in the production of energy and in bioresources.
