The synthesis of noble metal nanoparticles in various shapes and sizes is of high importance for many applications. Mostly, the preparation of these nanoparticles is done in aqueous solutions via a wet-chemical approach where micelle forming surfactants are involved as catalysts, structure directing agents and stabilizers. The main focus of roject A3 is to gain a deeper understanding of the interaction between inorganic noble metal nanoparticles and amphiphilic micelles. These interactions seem to play a crucial role in the formation, stabilization and degradation of such particles. We use small angle X-ray (SAXS) and neutron scattering (SANS) in combination with UV-Vis absorption spectroscopy and transmission electron microscopy to characterize the nanoparticles and micelles.
