Description
This research team is based on expertise in the development of functional materials (metal oxides, nitrides and oxynitrides) in the form of nanoparticles supported and integrated in organic matrices and nanostructured thin films. The objective is to develop materials with catalytic, photocatalytic and photonic properties. Three elaboration routes are currently considered according to the energy delivered to the material: soft chemistry (sol-gel process), plasma chemistry (spray-plasma process) and chemistry under extreme conditions (HP-HT processes). The team develops devices to optimize the targeted properties. The control of the elaboration processes requires the development of fundamental knowledge in the science of transfers at the interfaces: gas-liquid for the control of the nucleation and growth phenomena, spray-plasma for the control of the composition. Models are already being developed in collaboration with the THMR Team and other members of the laboratory.
