A facile procedure was applied to successfully synthesize novel Pd nanoparticles immobilized on tri-ethanolamine-functionalized magnetic nanoparticles [Fe3O4/IL/Pd]. Diverse characterizations (HR-TEM, XRD, FT-IR, TGA, EDX, FE-SEM, ICP, XPS and VSM) were carried out to identify intrinsic traits of the nanoparticles. At room temperature, Fe3O4/IL/Pd demonstrated high catalytic activity toward Suzuki-Miyaura cross-coupling reactions in aqueous solution. Based on the results, Fe3O4/IL/Pd acted as zwitt-erionic IL-type heterogeneous catalyst, which could be separated from the reaction mixture, conveniently. Moreover, it exhibited excellent recyclability for at least eight cycles without considerable loss of its activity. (C) 2017 Elsevier Ltd. All rights reserved.
