Abstract

Metallic nanoparticles are commonly used as the active phase of heterogeneous catalysts. Today, a current issue in catalysis research is to determine whether a specific crystallographic plane of the metallic nanoparticle is responsible for activity and selectivity properties in a structure sensible reaction. Following this purpose, metallic nanoparticles with specific morphologies have been studied. In the present work, palladium nanostructured particles are prepared in a surfactant mediated aqueous medium by a seeding growth approach, and present various morphologies : rods, tetrahedra and/or bipyramides, cubes, icosahedra... Synthesis of these nanoparticles and observation of their growth by a detailed Transmission Electron Microscopy study will be presented. We provide evidence that nucleation and growth of these particles are dominated by an aggregative mechanism. Moreover, upon ageing nanostructured particles undergo a ripening process to spherical morphology, attributed to an oxidative etching.
