将TiO2颗粒加入Ni-P镀液，用化学镀法在黄铜基底上制备不同TiO2含量的Ni-P-TiO2复合镀层电极。采用循环伏安法、线性扫描法、计时电流和交流阻抗法测试了Ni-P-TiO2/Cu电极的电化学性能。结果表明：常温下Ni-P-TiO2/Cu电极对碱性溶液中乙醇氧化有很高的电催化活性； Ni-P-TiO2电极上乙醇的电催化氧化活性随镀层TiO2量的不同而异，当镀液TiO2为5 g/L时，电极的乙醇电催化氧化活性最佳。

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.
