Poly (m-toluidine) (PMT) was prepared by oxidation of PMT in acidic aqueous solution in the presence of Triton X-100 (TX-100) at the surface of carbon paste electrode (CPE). Then transition metal of nickel was incorporated into the polymer by electrodepositing of Ni(II) from NiSO4 acidic solution using potentiostatic technique. The electrocatalytic oxidation of ethanol was studied by cyclic voltammetry and chronoamperometry methods at the surface of
obtained Ni/PMT(TX-100)/MCPE. The electrochemical characterization of this electrode exhibits redox behavior of Ni(III)/Ni(II) couple in alkaline medium. It has been shown that PMT/TX-100 film on the surface of the CPE improves efficiency of the catalyst toward the ethanol electrooxidation. The anodic peak current of ethanol oxidation increases with increasing ethanol concentration up to 0.4 M. Finally, the catalytic rate constant (k) for the
ethanol oxidation reaction was calculated 3.87 × 104 cm3 mol-1 s-1 by using a chronoamperometric technique
