PREPARATION AND CHARACTERIZATION OF PLATINUM NANOWIRES BY TEMPLATE-ASSISTED AC ELECTRODEPOSITION

摘要

In order to research the performance of platinum nanowire array electrode for electrocatalytic oxidation of methanol, anodic aluminum oxide (AAO) film was used as template to prepare platinum nanowires at first by alternative current (AC) electro-deposition. The morphology, elemental composition, micro-structure of Pt nanowires was characterized by SEM, TEM, SAED, EDS, XRD and XPS. The results indicated that the diameter of Pt nanowires was about 70nm, the nanowires were solid line without break, and their radial surfaces are not smooth. In addition, they are crystal structure and in the metallic state.
