摘要：
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.
