The Ni-P-TiO2 composite coating electrodes with different contents of TiO2 particulates were prepared by electroless plating technique from Ni-P plating bath containing TiO2 powders on brass. Cyclic voltammetry, linear sweep voltammetry (LSV), chronoamperometry and electrochemical impedance spectroscopy (EIS) were used to test the electrochemical performance of Ni-P-TiO2/Cu electrodes. It was indicated that the Ni-P-TiO2/Cu electrodes exhibited very strong electrocatalytic activity toward the oxidation of ethanol in alkaline medium at ambient temperature. The electrocatalytic activity of ethanol oxidation on the Ni-P-TiO2 electrodes depended on the amounts of TiO2 in the coatings. The excellent capacity on electrocatalytic oxidation of ethanol was obtained with the electrodes prepared in Ni-P plating bath containing 5 g?L-1 TiO2.
