文摘

We have successfully prepared a series of magnetically separable 鈥渜uasi-homogeneous鈥?Pd鈭扤i nanoalloy catalysts with tunable composition in a one-pot wet chemical route. We have evaluated the catalytic activity of these Pd鈭扤i alloy catalysts with different compositions through the Miyaura鈭扴uzuki 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.
