Abstract
Abstract
In this paper, Pt nanoparticles were successfully prepared by modified polyol method
using silver nitrate as an effective structure-modifying agent. The characterization
of Pt nanoparticles was investigated by using UV-Vis-NIR spectroscopy, transmission
electron microscopy (TEM) and high resolution (HR) TEM, and x-ray diffraction (XRD).
The method of selected area electron diffraction (SEAD) was used to study the
structure of Pt nanoparticles. The results showed that the as-prepared Pt
nanoparticles exhibiting the complexity of surface structure and morphology could be
used as efficient catalysts for polymer electrolyte membrane fuel cells (PEMFCs) and
direct methanol fuel cells (DMFCs).
