Title : Taking inspiration from molecular chemistry in nanochemistry to tune the properties of metal nanoparticles in catalysis

Abstract:

With the huge development of nanocatalysis, the demand for metal-based nanomaterials has been fast increasing and chemists are looking for effective synthesis methods to achieve well-defined nanocatalysts and to guarantee controllable and reproducible properties. Regarding nanochemistry in solution, the concepts of molecular chemistry allow developing efficient synthetic tools to have metal nanoparticles in a size less than 10 nm.Metal-organic complexes are particularly well-suited precursors to provide well-controlled and functionalized metal or metal-oxide nanoparticles in terms of size and composition. The choice of the stabilizing agent is of prime importance to control the characteristics of the nanoparticles and beyond, their surface properties. This method can be applied for the preparation of mono- or bimetallic nanocatalysts under the form of colloidal suspensions or supported systems. Selected examples of metal nanoparticles prepared through the organometallic approach will be presented with their performance in catalysis, respectively.

Biography:

After a PhD degree in Chemistry at the University of Toulouse-France and a postdoctoral position at the catalysis department of Rhodia-Lyon, Dr. Karine Philippot integrated CNRS. She is presently Senior Researcher at the Laboratory of Coordination Chemistry (LCC) in Toulouseand head of the team “Engineering of Metal Nanoparticles”. Her research interests deal with the synthesis of metal nanoparticles and composite nanomaterials by using molecular chemistry concepts for their application in colloidal or supported catalysis and in the domain of energy. She is co-author of >160 peer reviewed papers (with 5 reviews, 13 proceedings, 9 book chapters, 6 patents) and co-editor of the book “Nanomaterials in Catalysis” (Wiley)
