Material design and synthesis

published on , updated on


One of the LSFC research topics is ceramic material synthesis, for materials having various applications in environmental catalysis and energy production (e.g. mixed, ion or proton conductors, heterogeneous catalysis, support materials). Specific applications demand precise properties of the materials. Tailored synthesis routes can lead to the desired material having a specific chemical composition, surface area, structural property or morphology. We use a variety of different synthesis routes, including hydrothermal synthesis, co-precipitation, sol-gel synthesis and combustion.

Specific functions can also be given to a support material by depositing catalytic sites on its surface or coating it with thin functional layers. Specific functions can also be given to a support material by depositing catalytic sites on its surface or coating it with thin functional layers.

As an example, we work on the washcoating of particulate filters (figure 1) for automotive applications, in particular in the frame of the ANR project TRIPTIC-H. To achieve good coatings without clogging (figure 2), we control the colloidal stability of the coating suspensions and the interactions with the support material.

When materials or coatings characterization requires specific techniques, analysis is carried out in collaboration with other research institutes. For example, we are part of the Centre commun de microscopie de Lille and we have established a collaboration with IM2NP for tomographic atomic probe analysis.
