Glass Carbon Electrode Modified with Nanocrystalline Nickel-decorated Carbon Nanotubes and Its Electrocatalysis of Methanol Oxidation in Alkaline Solution
Abstract:
Nanocrystalline nickel with an average diameter of about 16 nm and a face-centered cubic (fcc) structure were uniformly attached to the surface of multi-wall carbon nanotubes by wet chemistry,and the product was characterized by X-ray power diffraction and transmission electron microscopy.A glass carbon electrode modified with the nickel-decorated carbon nanotubes (MWCNTs-Ni/GCE) was prepared.The electrochemical behavior of the MWCNTs-Ni/GCE and the electrocatalytic oxidation of methanol at the MWCNTs-Ni/GCE were investigated by means of cyclic voltammetry in 1.0 mol/L NaOH solution.The cyclic voltammetry showed the electron transfer of β-Ni(OH)2⇋β-NiOOH is mainly a diffusion-controlled quasi-reversible process,and the high catalytic activity of the electrode for the electro-oxidation of methanol in alkaline medium suggests its potential application in alkaline rechargeable batteries and fuel cells.
