Abstract
The voltammetric behaviour of electropolymerized nickel macrocyclic complexes in alkaline aqueous solution is described. The nickel-based modified electrodes were prepared by oxidative polymerization of nickel porphyrin, nickel salen and nickel cyclam complexes by repeated potential scans in 0.1 m NaOH solution. All the electroformed films exhibited the same behaviour which is similar to that shown by nickel hydroxide-modified electrodes. In addition, the nickel complex-based polymers act as efficient materials for the electrocatalytic oxidation of methanol, ethanol and hydrazine.
