Title : How the design of nanomaterials allows to control their properties

Abstract:

Emergence of nanotechnology increasingly shows examples of the material potentiality which has, at least one dimension less than 100 nm. The preparation of nano-objects by soft chemistry in aqueous solution with crystal structure, size and morphology perfectly controlled is based on the use of molecular precursors and adjustment of physico-chemical parameters (acidity, ionic strength, temperature…) during the precipitation of the solid. The growth of nano-crystals can be limited or favoured in some crystallographic directions. It is also possible to involve redox processes in addition to the acido-basic reactions. That can significantly enhance the potentiality of this chemistry in the design of particles. Furthermore, the synthesis of hierarchical materials with multiple scales of organization and often formed from the assembly of nanoparticles, raises a growing interest, mainly thanks to their ability to combine the functions of the various elementary units. This allows to consider interesting applications of these systems in various fields and especially in the field of Energy, either for conversion or storage and (photo)catalysis.

Audience Take Away:

  • Show the versatility of soft chemistry to control the formation of functional nanoparticles.
  • Show how the design of materials can control their properties.
  • Present some examples of application in energy and (photo)catalysis.
