中文摘要：
以电合成前驱体Ti（OEt）4直接水解法和电沉积法制备Ti基纳米TiO2-碳纳米管复合膜载Pt（Pt/nanoTiO2-CNT）复合电极。透射电镜（TEM）和X射线衍射（XRD）测试表明，锐钛矿型纳米TiO：粒子和Pt纳米粒子（粒径约8nm）均匀地分散在碳纳米管表面。通过循环伏安法研究Pt/nanoTiO2-CNT电极对Ce^3＋的电催化性能，Ce^3＋氧化峰电位约为1．27V（vs．SCE），比Pt／nanoTiO2电极负移30ml/峰电流约高45mA·Cm^＋2。
英文摘要：
The Pt/nanoTiO2-CNT complex electrodes were prepared by precursor of Ti （OEt）4 directly hydrolyzed and electrochemical deposition technique. The results of XRD and SEM showed that the nanoTiO2 （anatase） and Pt nanoparticle （size about 8 nm） is dispersed uniformly on CNT film surface.The electrocatalytic activity of Pt/nanoTiO2-CNT electrode to Ce^3＋ was investigated by cyclic voltammetry curves.The oxidation peak potential of Ce^3＋ was 1.27 V ,which is 30 mV of negative-transfering as compared with Pt/nanoTiO2 electrode.The corresponding oxidation peak current was high 45 mA.cm^-2.
