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


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.


Sophie Cassaignon is Professor in Materials Chemistry at Sorbonne University (Paris, France). She received his B.Sc and M.Sc, in Chemistry from UPMC (Now Sorbonne University). She received her PhD degree in 1998 at the same institution. Currently, she is working in the Laboratory of the Condensed Matter of Paris and her research interests are nanomaterials synthesis, conversion/storage of Energy and (photo)catalysis. She has published more than 60 research articles in peer-reviewed journals.
