Highly ordered Pd nanowire arrays (NWAs) prepared by electrodeposition method using the fresh prepared anodic aluminum oxide (AAO) as the template have been characterized by X-ray diffraction pattern (XRD), X-ray photoelectron spectroscopy (XPS), transmission electron microscope (TEM), scanning electron microscopy (SEM), and electrochemical measurements. SEM results revealed that the brush-shaped Pd NWAs are dispersed uniformly. The diameter and length of the obtained Pd NWAs are about 50 nm and 850 nm, respectively. Furthermore, the electrocatalytic activity of Pd NWAs electrode for propanol oxidation in alkaline media has also been studied. It is found that the obtained nanostructurs exhibit excellent electrocatalytic activity toward the oxidation of propanol, demonstrating the potential application in portable direct alcohol fuel cells (DAFCs).
采用新鲜制备的阳极氧化铝（AAO）作为模板，通过电沉积法制备的高度有序钯纳米线阵列（NWAs），已通过X射线衍射图谱（XRD）、X射线光电子能谱（XPS）、透射电子显微镜（TEM）、扫描电子显微镜（SEM）和电化学测量进行了表征。SEM结果表明，刷状钯纳米线阵列均匀分散。所制备的钯纳米线阵列的直径和长度分别约为50nm和850nm。此外，还研究了钯纳米线阵列电极在碱性介质中对丙醇氧化的电催化活性。结果发现，所制备的纳米结构对丙醇氧化表现出优异的电催化活性，表明其在便携式直接醇类燃料电池（DAFCs）中的潜在应用。
