PdCo bimetallic nanoparticles (NPs) were decorated over three‐dimensional graphene (3DG) in a facile manner by reducing palladium chloride and cobalt chloride in the presence of ethylene glycol as reducing, stabilizing and dispersing agent. The PdCo NPs–3DG nanocomposite was characterized using Raman, X‐ray photoelectron and energy‐dispersive X‐ray spectroscopies, X‐ray diffraction and transmission electron microscopy. The obtained catalyst can act as an efficient catalyst for Sonogashira cross‐coupling reactions in aqueous media.
