摘要：

In the presence of the protective polymer poly(N-vinyl-2-pyrrolidone)(PVP), PVP-protected palladium-gold bimetallic colloids were obtained by refluxing a CH3OH-H2O (1:1 by volume) solution of palladium chloride and chloroauric acid. The resulting bimetallic colloids catalyzed the selective partial hydrogenation of cis,cis-1,3-cyclooctadiene (COD) and the hydrogenolysis of p-nitrotoluene with activities about 2.4 times and 3.6 times those of monometallic palladium colloid, respectively. These bimetallic colloids were characterized by TEM, XRD and XPS. The TEM and XRD data elucidated the formation of bimetallic colloids. XPS data indicated that the constituent elements were in the metallic state and that palladium atoms were concentrated on the surface of the alloy cluster.
