Abstract

A novel chemical modified nickel (Ni) electrode based on multi-walled carbon nanotubes (MWCNTs), Nafion film and nickel hydroxide has been successfully fabricated for methane (CH₄) detection at ambient conditions. The morphology of the MWCNTs-Nafion/Ni(OH)₂ film was characterized by transmission electron microscopy and the electrochemical properties of the Ni modified electrode were studied by cyclic voltammetry. The MWCNTs-Nafion/Ni(OH)₂-Ni electrode showed good catalytic effect on the oxidation of CH₄ in 1.0 M NaOH. In addition, the modified electrode was free from nitrogen and oxygen interferences. When differential pulse voltammetry was applied to the MWCNTs-Nafion/Ni(OH)₂-Ni electrode, a good linear relationship between the oxidation peak current (i) and CH₄ concentration (C_methane) was obtained: i = 1.841C_methane + 46.25, where i is in μA and C_methane is in 0.0-16.0% (v/v). The relative standard deviation for detection of 3.0% (v/v) CH₄ was 1.80% (n = 5). The proposed Ni modified electrode is anticipated to provide a promising technique to detect CH₄ at ambient conditions.
