Matériaux inorganiques

The research in the Inorganic Materials (MI) thematic area is focused on homogeneous or composite inorganic materials. These materials, essentially oxides and fluorides, are elaborated in the form of micro or nanometric powders, massive objects or thin layers. They can be crystallized, amorphous or glass-ceramic. The objectives of our research are to determine their intimate organization at the atomic scale and its consequences on functionalities/properties that can lead to applications in the fields of energy, environment and more recently in the field of health. Thus, our materials can contribute to the energy transition by using them in devices that extract energy from chemical reactions (batteries, fuel cells) or transform light energy into electrical energy (photovoltaic). Our materials have also proven to be efficient as catalysts for the synthesis of organic molecules and for the electro-catalytic oxidation of water, thus contributing to the development of more energy-efficient processes. Our activities in the environmental field concern the chemical capture of CO2 and the photo-catalytic degradation of organic pollutants in water. Finally, the development of inorganic bactericidal agents with low ecotoxicity should make it possible to fight against nosocomial infections while being more respectful of the environment.

Structural determination by diffraction on single crystals or powders as well as the synthesis of fluorides are two internationally recognized historical skills of our thematic. Our thematic also has proven skills to improve its knowledge of the organization of matter at short and long distances: Transmission Electron Microscopy, solid state NMR and EPR spectroscopies and modeling. We also characterize the electrical properties of our materials by complex impedance spectroscopy, their magnetic properties by Mossbauer spectroscopy and their vibrational properties by Raman spectroscopy. These last two properties are the subject of collaboration with the PSC thematic. Our internal collaborations at IMMM are not limited to the PSC thematic. Indeed, we call upon the competences of colleagues of the SO and POL thematics for the elaboration of original ligands with multiple tetrazolic rings and polymer beads as template in the elaboration of MOF (Metal organic Frameworks) and OPIF (Organized Porous Inorganic Fluorides), respectively.

The activities are organized in 3 axes and 8 research actions.
