Abstract

In this communication we report the synthesis, characterization and applications of TeNTs decorated with PtNPs readily prepared by two simple steps to make a GC modified electrode suitable to be used as anode/cathode in fuel cells. In the 1th step the large scale of Te nanotubes synthesis was obtained via a vapor deposition method; then in the 2nd step TeNTs dispersed in methanol react with PtCl2 to make TeNTs/PtNPs. Modified electrodes TeNTs/PtNPs/GC were then made by casting 20 μL of TeNTs/PtNPs/ethanol suspension onto GC surface and left to evaporate at room temperature. The as synthesized hybrid nanostructures, fully characterized by XRD, TEM and XPS analysis, were composed of Te nanotubes decorated with Pt nanoparticles. The electrochemical characterization of TeNTs/PtNPs composite material, performed by cyclic voltammetry (CV), showed exceptional electrocatalytic activity towards methanol oxidations and oxygen reduction.

铂纳米粒子修饰纳米管在燃料电池中的应用
在这篇通讯中,我们报告了用PtNPs修饰的tent的合成,表征和应用,这些PtNPs很容易通过两个简单的步骤制备,从而使GC修饰电极适合用作燃料电池的阳极/阴极。第1步采用气相沉积法制备了大规模的纳米管;第二步,分散在甲醇中的tent与PtCl2反应生成tent /PtNPs。在GC表面浇铸20 μL的tent /PtNPs/乙醇悬浮液,室温蒸发,制成修饰电极tent /PtNPs/GC。通过XRD、TEM和XPS分析对合成的杂化纳米结构进行了表征。循环伏安法(CV)表征了tent /PtNPs复合材料对甲醇氧化和氧还原的电催化活性。
