Abstract
This paper deals with the synthesis of Pt and Pt/Pb nanoparticles via oil-in-water microemulsions. Studying systematically the phase behavior of microemulsions which contain metal precursors, it was possible to determine the influence of the metal precursors on the phase behavior of the base microemulsion. It was found that the addition of Pb(ethylhexanoate)2 to the microemulsion shifts the phase boundaries to slightly lower temperatures, while adding dimethyl-(cyclooctadiene) platinum has no effect on the phase boundaries. SAXS measurements confirmed that the addition of the metal precursors does not influence the size of the microemulsion droplets along the emulsification failure boundary. Using transmission electron microscopy (TEM) we found that by increasing the oil content wB in the microemulsion from 0.04 to 0.08 the size of the resulting mono- and bimetallic Pt and Pt/Pb nanoparticles changes from 3 to 4.4 nm.
