In our group, the synthesis of metal nanoparticles is performed through an organometallic approach. Metal organic complexes are decomposed in solution under mild conditions and in the presence of ligands as stabilizing agents. Our objective is to obtain well-dispersed nanoparticles with a narrow size distribution and a controlled surface composition, these parameters being important in catalysis. The choice of the ligand used as stabilizer is thus of prime importance as it can influence the properties of the nanoparticles, as their size, shape, or surface chemistry.Examples of so-obtained nanoparticles will be presented. A particular attention will be devoted to the functionalisation of their surface that can lead to application in the field of catalysis, in organic1 or aqueous media,2 depending on the ligands used as stabilizers.1    M.Zahmakiran, M.Tristany, K.Philippot, K.Fajerwerg, S.�zkar, B.Chaudret, Chem.Commun. 2010, 17, 2938.2    M.Guerrero, A.Roucoux, A.Denicourt-Nowicki, H.Bricout, E.Monflier, V.Colli�re, K.Fajerwerg, K.Philippot, Catal.Today, 2011, in press.
