Preparation of Pt Nanofibers by Electrospinning |
| 초록 |
We report a simple and practical method for preparing one-dimensional nanostructure of platinum via electospinning of Pt precursor/polymer composite fibers, followed by subsequent thermal annealing. The resulting Pt nanofibers(NFs) had diameters less than 100 nm with lengths up to several hundreds micrometers. The internal morphologies of Pt-NFs were governed by thermal annealing condition. The internal morphology change of Pt-Nfs with respect to the thermal annealing conditions was characterized using high resolution transmission electron microscopy (HR-TEM) and scanning electron microscope (SEM) and in-situ high temperature X-ray diffraction (HT-XRD). Room-temperature current-voltage (I-V) characteristics showed that the single Pt-NFs exhibits metallic conductivity and it is clearly correlated to the internal grain structure. |
