This paper develops a green method for in situ decorated of palladium nanoparticles over Fe 3 O 4 nanoparticles, by utilizing Strawberry fruit extract and ultrasound irradiations, with no use of any toxic reducing agent. The structure's characterization is represented via diverse analytical methods such as FT‐IR, FE‐SEM, TEM, WDX, ICP, EDS and XXPS. Catalytic efficiency of magnetic Fe 3 O 4 @ Strawberry /Pd nanocatalyst is investigated in production of different biphenyls with good turnover frequencies (TOF) and turnover numbers (TON) through Suzuki coupling reactions. Furthermore, the catalyst could be recovered and reused 7 runs without considerable palladium leaching or alteration in its performance.
