中文摘要：
于Ni-P镀液添加TiO2颗粒,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定Ni-P-TiO2/Cu电极的电化学性能.结果表明：常温下Ni-P-TiO2/Cu电极在碱性溶液中对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;镀液中TiO2含量为5 g.L-1时,所得电极的电催化乙醇氧化的活性最佳.
英文摘要：
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,chronoamperometry and electrochemical impedance spectroscopy 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.
