A new fourth-generation poly (propylene imine) dendrimer (G4-M) contaimng 32 triolefinic 15membered macrocycles on the surfaces has been synthesized. The bimetallic R dendrither-stabilized nanoparticles (DSNs) were first prepared within G4-M by a co-complexation route. The new G4-M dendrimer has been characterized by IH nuclear magnetic resonance, infrared radiation, and elemental analysis. The dendrimer-stabilized bimetallic ions and reduction courses were analyzed by UV-vis spectroscopy. Highresolution transmission electron microscopy and energy dispersive spectrometer were used to characterize the bimetallic nanoparticle size, size distribution, and particle morphology. The Rath bimetallic DSNs showed high catalytic activity for the hydrogenation of nitrile-butadiene rubber.
