This manuscript reports the design, synthesis and application of naturally occurring cellulose, generated from agro waste pomegranate peel, as novel support for active biogenic Pd (0) nanoparticles (NPs) for room temperature Suzuki-Miyaura and Sonogashira cross-coupling reactions. The presence of hydroxyl groups and unsaturated hanging bonds on their surfaces in cellulose matrix enable well dispersion of PdNPs over the support matrix to generate Pd@cellulose. This in turn exhibits excellent catalytic activity, easy removal from the reaction mixture, recyclable without loss of catalytic activity for Suzuki-Miyaura and Sonogashira reactions under ligand-free mild reaction conditions. The synthesized cellulosic nanofibers and Pd-anchored heterogeneous nanofibers were characterized by SEM, EDX, TEM, Powder XRD, FT-IR spectroscopy and BET surface analysis. |
