▎ 摘　　要

Highly monodisperse graphene oxide-supported Ru/Pd nanoparticles (RuPd@GO NPs) have been reproducibly and easily synthesized by microwave assisted method. RuPd@GO NPs was performed for dehalogenation of arylhalides in the presence of ammonia borane in a mild condition as novel, highly efficient and exceptional reusable heterogeneous catalyst. The novel materials were characterized by transmission electron microscopy (TEM), the high resolution electron micrograph (HRTEM), X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS). The results showed that the prepared catalysts are highly crystalline, monodisperse and colloidally stable. The current one-pot catalytic process was described as a new methodology for dehalogenation of arylhalides which can be assessed as a quite simple, eco-friendly and highly efficient as well as exceptional reusable. All products were provided with one of the highest yield and the shortest time in the presence of novel RuPd@GO NPs due to the the synergistic effect of Ru and Pd. Our synthesis process comes with a facile and eco-friendly option to RuPd@GO NPs, allowing further scrutiny of current catalysts for numerous other chemical reactions.
