| 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P(tPt/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TiO2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Ce3+的电催化性能,Ce3+氧化峰电位约为1.27V(vs.SCE),比Pt/nanoTiO2电极负移30mV,峰电流约高45mA·cm-2。

| Abstract: | 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 Ce3+ was investigated by cyclic voltammetry curves.The oxidation peak potential of Ce3+ was 1.27 V ,which is 30 mV of negative-transfering as compared with Pt/nanoTiO2 el... |
