Stabilization of Pd nanoparticles in inverse microemulsions

Pd nanoparticles were prepared by reduction with ethanol of palladium acetate stabilized tetradodecylammonium bromide (TDABr) tetrahydrofurane (THF) as dispersion medium. Inverse microemulsions were also prepared in THF/TDABr/H2O system with different water diameter and the structure of complex liquids was investigated by densitometer. Nanosized Pd-0 particles were synthesized in the water pool of micellar system. The Pd-0/surfactant system absorption spectroscopy characterized by transmission electron microscopy. It was that at the liquid/liquid and (nanoparticle) surfaces the adsorbed surfactant provied very high excess volume compression in compression in the nanodisperse system.
