摘要：

Pd-Pt bimetallic colloids were prepared by reduction of their corresponding salts extracted in organic solvents (cyclohexane, chloroform) with hydrazine or sodium boron hydride. Two extractants were used: trioctylphosphine oxide (TOPO) and distearyldimethylammonium chloride (DDAC). In both organic solvents, the particle size of Pd-Pt colloids depended on the feed molar fraction of Pd using hydrazine, but almost was independent on the feed molar fraction of Pd using boron hydride. The dispersion stability of Pd-Pt colloids increased as the particle size decreased.
