Electrochemical fabrication of a novel conducting metallopolymer nanoparticles and its electrocatalytic application
Present article is the first example of a novel two step electrochemical route for fabrication of nanoparticles of conducting metallopolymer of Ni-curcumin (Ni-Curc-NPs). Firstly, nickel nanoparticles (Ni-NPs) were electrochemically deposited on the electrode surface. Then, electropolymerization of Ni-Curc-NPs were performed at the electrode modified with Ni-NPs. These nanostructures were characterized using electrochemical methods including cyclic voltammetry (CV), electrochemical impedance spectroscopy (EIS) and hydrodynamic amperometry, also surface analysis methods and electron microscopy including energy dispersive analysis of X-ray (EDAX), X-ray photoelectron spectroscopy (XPS) and scanning electron microscopy (SEM). Additionally, application of the Ni-Curc-NPs modified electrode toward glucose electrooxidation was examined. A lower limit of detection and enhanced dynamic linear range for determination of glucose were observed at Ni-Curc-NPs modified electrode compared to Ni-NPs modified electrode. (C) 2013 Elsevier Ltd.
