Materials (metal, oxides, clays, zeolithes, carbonated supports, ….)

The research on material whose properties are predetermined (from synthesis or of natural origin) requires perfectly-defined processes of preparation and modification , coupled with analysis tools and high-resolution modeling, at the nanometric and macroscopic scale .

This strategy matches perfectly with the themes developed within the various teams whose expertise has been internationally recognized for many years, particularly in the area of clays and catalytic materials.

Therefore, a common field of investigation includes the work of different teams: the synthesis, crystal chemistry, reactivity, modeling, characterization as multi-scale material properties.

This complementarity asset has recently led to joint actions (actions incentives, CPER environmental industries, joint supervision of students …). The first results have already been seen and take the form of publications and lectures made at several international conferences.

– For example, the elaboration of original materials based on the use of synthetic clays has already improved the catalytic properties in the energy field (synthesis of clean fuels, reforming) and also in the field of specialty chemicals (recovery of glycerol).

– Using atomistic calculations in the modeling of physico-chemical surface of clay minerals has also improved the capacity to predict the excitability of these phases, especially toward water and organic molecules.

In addition to the benefits of this approach for the application “Materials”, it is also important to notice the reactivity of clay minerals in natural systems, especially toward water and pollutant (T3 cross thematic action ).

Moreover, the rearrangement of dedicated preparation materials and their establishment are essential for any application at a larger scale. This is an area rarely addressed in France, but it nonetheless requires fundamental studies, especially for new materials. The validation of this work (scale transfer and shaping) can be carried out in the framework of the platform created by the PREMICAT LACCO to generate materials “ready to use.”
