Monodispersed Pd-Ni nanoparticles: composition control synthesis and catalytic properties in the Miyaura-Suzuki reaction.

We have successfully prepared a series of magnetically separable "quasi-homogeneous" Pd-Ni nanoalloy catalysts with tunable composition in a one-pot wet chemical route. We have evaluated the catalytic activity of these Pd-Ni alloy catalysts with different compositions through the Miyaura-Suzuki coupling reaction. These palladium/non-noble metal alloy catalysts show better catalytic activity than an equal amount of palladium nanoparticles. Furthermore, these catalysts exhibited excellent performance in superparamagnetism owing to its great advantage for reducing the usage of noble metal.
