Description
Summary:Synthesis, characterization and catalytic application of a novel graphene oxide supported Schiff–base/palladium complex are developed [Display omitted] In the current research, preparation, characterization and catalytic application of a novel Schiff-base/Pd complex immobilized onto graphene oxide (GO–SB/Pd) are investigated. The GO–SB/Pd was characterized using Fourier transform infrared spectroscopy, thermal gravimetric analysis, diffuse reflectance UV–Vis, Raman spectroscopy, scanning electron microscopy (SEM), transmission electron microscopy (TEM) and energy-dispersive X-ray (EDX) analysis. It was found that the GO–SB/Pd is an efficient catalyst in the Suzuki–Miyaura cross-coupling of phenylboronic acid with aryl halides. Moreover, the catalyst could be easily recycled and reused for several times without discernible loss in activity.
