Electrocatalytic oxidation of methanol on the surface of the POAP/ ionic liquid-functionalized graphene oxide nanocomposite modified graphite electrode

In situ electropolymerization as a facile synthetic procedure has been used to obtain highly sensitive composites of ionic liquid functionalized graphene oxide (FGO) and poly ortho aminophenol (POAP). Nickel was accumulated by complex formation between Ni (II) in solution and amines sites in the polymer backbone to obtain Ni-FGO-POAP/G (graphite) electrode. Surface morphology of composite was characterized by scanning electron microscopy. The electrochemical performance of Ni-FGO-POAP composite electrodes was investigated by common electrochemical techniques. Compared with Ni- POAP, a Ni-FGO-POAP electrode shows a higher catalytic performance in the electrocatalytic oxidation of methanol. Developing a simple and green route for synthesis of POAP/FGO and long life cycle and stability of nanocomposite are main important factor in presented work.
