摘要/Abstract

摘要：

采用静电纺丝技术结合还原浸渍法制备了Pt/TiO₂纳米纤维电催化剂, 通过X射线衍射(XRD)分析、扫描电镜(SEM)、透射电镜(TEM)和X射线能谱(EDS)等测试手段对样品的晶相、形貌、微结构和化学组成进行了表征. 测试结果表明, TiO₂纳米纤维为锐钛矿和金红石组成的混晶, Pt 纳米颗粒均匀地分布于TiO₂纳米纤维的表面, 且Pt 颗粒大小较均一, 平均粒径为4.0 nm, Pt/TiO₂纳米纤维中Pt 的质量分数约为20%. 采用三电极体系的循环伏安和计时电流电化学分析方法研究了样品在酸性溶液中对甲醇的电催化氧化活性, 结果表明, 与负载相同质量分数Pt 的Pt/P25 和商业Pt/C 催化剂相比较, Pt/TiO₂纳米纤维催化剂对甲醇呈现出较高的电催化氧化活性和更好的稳定性.

Abstract:

A Pt/TiO₂ nanofiber catalyst has been prepared through the combination of an electrospinning technique with a reductive impregnation method. The compositions, morphologies and structures of the samples were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), and energy dispersive spectroscopy (EDS). The results showed that the crystal phase of the TiO₂ nanofibers was composed of anatase and rutile TiO₂. Pt nanoparticles were found to be uniformly distributed on the surface of the TiO₂ nanofibers with an average size of 4.0 nm. The mass fraction of Pt in the Pt/TiO₂ nanofiber catalyst was about 20%. The electrocatalytic activities of the samples towards the oxidation of methanol were measured by cyclic voltammetry and chronoamperometry using a three-electrode system in an acidic solution. Compared with Pt/P25 and commercial Pt/C catalysts containing the same quality percentage of Pt nanoparticles, the Pt/TiO₂ nanofiber catalyst exhibited higher catalytic activity towards the oxidation of methanol and better stability.
