Cu nanoparticles (NPs) supported on graphene (G) obtained by pyrolysis of alginate is a highly active catalyst for the A3 coupling of aldehydes, secondary amines and terminal acetylenes. Adsorption of Cu NPs previously formed by the polyol method onto dispersed G in ethylene glycol was found a suitable procedure for the preparation of a highly active catalyst. Cu/G undergoes gradual deactivation upon
