Abstract: <smarttagtype namespaceuri="urn:schemas-microsoft-com:office:smarttags" name="chmetcnv"><smarttagtype namespaceuri="urn:schemas-microsoft-com:office:smarttags" name="metricconverter"> 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 <i style="">M</i> CH<sub>3</sub>CH<sub>2</sub>OH + 0.5 <i style="">M</i> H<sub>2</sub>SO<sub>4</sub> 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</smarttagtype></smarttagtype>
