摘要：

The voltammetric behavior of carbon electrodes coated by a nickel macrocyclic complex-based film in alkaline aqueous solution is described. The nickel-based modified electrodes were prepared by anodic oxidation of nickel porphyrin and nickel cyclam complexes by repeated potential scans in 0.1 M NaOH aqueous solution. The nickel-based films act as efficient materials for the electrocatalytic oxidation of alcohols and phenol derivatives in aqueous 0.1 M NaOH and prevent the electrode from irreversible passivation during the electrocatalytic oxidation of phenols in neutral aqueous solution.
