“…Contrastingly, there is no report available till date for the synthesis of bio-reduced graphene oxide supported bimetallic Pd/Cu nanocomposite and investigation of its heterogeneous catalytic potentiality in Sonogashira cross-coupling reaction in ethanol. From this point of view and in continuation of our previous works as well, 33,[45][46][47][48][49] here we report the synthesis and characterization of ligand-free, Pd-Cu bimetallic nanoparticles supported on graphene oxide by bio reduction method and its application in Sonogashira cross-coupling reaction.…”
