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