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
