Preparation, Characterization and First Application of Graphene Oxide‐Metformin‐Nickel for the Suzuki Cross‐Coupling Reaction

Abstract In this project, in the first step, the graphene oxide‐metformin‐nickel catalyst has been prepared and then the Ni(II) was reduced to Ni(0) by hydrazine hydrate and Ni(0) nanoparticle coordinated to metformin‐GO was achieved. After full characterization of catalyst structure by different analyses like fourier‐transform infrared spectroscopy (FT‐IR), transmission electron microscopy (TEM), scanning electron microscopy (SEM), energy dispersive X‐Ray analysis (EDX), X‐Ray diffraction analysis (XRD), thermal gravimetric analysis (TGA), and coupled plasma/atomic emission spectroscopy (ICP), as well as confirm the successful synthesis of catalyst, the activity of catalyst has been examined in the Suzuki–Miyaura cross‐coupling reaction.
