| Abstract: |
Carbon nanotube supported Pt-Sn nanoparticles have been prepared by using a
replacement reaction method. The micrography, elemental composition and
structure analysis of Pt-Sn catalysts have been studied by scanning electron
microscopy, energy dispersive X-ray spectroscopy and X-ray diffractograms,
respectively. The electrocatalytic activity of Pt-Sn/CNTs for ethanol electrooxidation
has been investigated by cyclic voltammetry in 1.0 M CH3CH2OH + 0.5 M
H2SO4 solution. The results show that the obtained
Pt-Sn/CNT nanoparticles exhibit higher electrocatalytic activity and better
long-term stability for ethanol oxidation as compared to the PtSn/CNT nanoparticles
prepared by the conventional coreduction method |
