Synthesis of Au/Pd bimetallic nanoparticles and their application in the Suzuki coupling reaction

•Preparation of Au/Pd bimetallic nanoparticles as efficient and reusable catalysts.•The catalyst was investigated by SEM and EDS.•Ligand-free Suzuki coupling reactions.•Operational simplicity, elimination of ligand and homogeneous catalysts and high yields. This communication reports on the synthesis and use of Au/Pd bimetallic nanoparticles, as separable catalysts for ligand-free Suzuki coupling reactions. This method has the advantages of high yields, elimination of homogeneous catalysts, green reaction conditions, simple methodology and easy work up. Catalytic efficiency remains unaltered even after several repeated cycles. The catalyst was characterized using the SEM and EDS.
