We have developed a novel one-pot synthetic procedure for monodisperse palladium tin bimetallic alloy nanoparticles (NPs) with tunable compositions and sizes by the co-reduction of tin(II) acetate and palladium(II) bromide in the presence of oleylamine and trioctylphosphine. These NPs loaded on active carbon (PdSn/C) were used as active catalysts for Heck reactions, and exhibited composition dependent catalytic activities. Among these nanocatalysts, Pd₆₃Sn₃₇ NPs showed the best catalytic performance which is even superior to pure Pd NPs. Graphical Abstract PdSn NPs with controlled compositions and sizes were synthesized and characterized systematically, and Pd₆₃Sn₃₇/C NPs showed the best catalytic ability and stability that is even superior to pure Pd NPs with higher catalytic activity and stability in multi-recycled Heck reactions.
