PdPt bimetallic nanoparticles stabilized by 15-membered triolefinic macrocycle-stabilized poly(propylene imine) dendrimer (G3-M(PdxPt10−x) DSNs) have been prepared via synthesis of a 15-membered triolefinic macrocycle-modified third-generation poly(propylene imine) dendrimer (G3-M) and then synchronous ligand exchange with Pd(PPh3)4/Pt(PPh3)4 complexes. The structure and catalytic activity of the DSNs were characterized using Fourier transform infrared, 1H NMR, transmission electron microscopy, energy-dispersive X-ray and X-ray photoelectron analyses. As a novel catalyst system, it can be concluded that the composition of the bimetallic nanoparticles has an influence on the catalytic activity of the hydrogenation reaction of acrylonitrile–butadiene rubber, which can be related to synergistic effect. Furthermore, the selectivity and recyclability of G3-M(PdxPt10−x) DSN catalyst are also discussed.
