High Electrocatalytic Performance of CuCoNi@CNTs Modified Glassy Carbon Electrode towards Methanol Oxidation in Alkaline Medium
A novel non-precious multiwalled carbon nanotubes (CNTs)—supported metal oxide electrocatalyst was developed for methanol electrooxidation in alkaline medium. The catalyst was fabricated by simultaneous electrodeposition of copper-cobalt-nickel ternary nanostructures (CuCoNi) on a glassy carbon electrode (GCE) modified with CNTs. The proposed electrode was characterized using X-ray diffraction ...
متن کاملElectrocatalytic oxidation of methanol on platinum modified polyaniline electrodes
Electrocatalytic oxidation of methanol on Pt modified polyaniline electrodes was investigated with the aim of developing highly active composite electrodes for direct methanol fuel cells. Cyclic voltammetry and chronoamperometry were used to evaluate the catalytic activity in sulfuric acid solutions containing methanol. Pt / polyaniline modified carbon electrodes showed higher catalytic activit...
متن کاملApplication of copper oxide nanoparticles modified glassy carbon electrode for electrocatalytic oxidation of methanol
Copper nanoparticles were fabricated by electro-reduction of CuSO4solution in the presence of cetyltrimethylammonium bromide (CTAB) cationic surfactant as an additive through potentiostatic method. The prepared copper nanoparticles were characterized by scanning electron microscopy (SEM) and electrochemical methods. The SEM images reveal that the nanoparticles with diameters at about 70 n...
متن کاملN O T E S Electrocatalytic Oxidation of Ethanol on Platinum Nanoparticles Modified Polyaniline Electrode
−− The electrocatalytic properties of platinum nanoparticles incorporated into polyaniline films was investigated for oxidation of ethanol in sulfuric acid solutions. The electropolymerization of aniline and the electrochemical depositions of platinum particles into the polyaniline film were achieved by cyclic voltammetry. The effect of the formation conditions of platinum-modified polyaniline ...
متن کاملEffect of Ni Core Structure on the Electrocatalytic Activity of Pt-Ni/C in Methanol Oxidation
Methanol oxidation catalysts comprising an outer Pt-shell with an inner Ni-core supported on carbon, (Pt-Ni/C), were prepared with either crystalline or amorphous Ni core structures. Structural comparisons of the two forms of catalyst were made using transmission electron microscopy (TEM), X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS), and methanol oxidation activity compar...
