Palladium nanoparticles immobilized on Schiff base‐functionalized graphene‐oxide (GO−Pd) has been synthesized and characterized by FT‐IR, Raman, PXRD, UV‐Visible, TGA, XPS, FE‐SEM, TEM, EDAX, Elemental mapping, BET, AAS and ICP MS analysis. The GO−Pd showed promising catalytic activity for the Suzuki‐Miyaura, Hiyama and Heck‐Mizoroki coupling reactions with higher yields (up to 95%). GO−Pd can be easily filtered out from the reaction mixture and reused up to six times without significant loss of catalytic activity. All of the synthetic products obtained were fully characterized from their spectral data.
