| Abstract: | The Pt-Sn/C catalyst was synthesized with the direct Thermo-decomposition method using Pt(NO3)2 and SnO as the precusors. The Pt-Sn/C catalyst was characteristed with X-ray diffraction(XRD), transmission electron microscopy(TEM) and X-photoelectron spectroscopy(XPS). The electrocatalytic performance of the Pt-Sn/C catalyst was investigated with the cyclic voltammetry. It was found that the Pt-Sn particles in the Pt-Sn/C catalyst prepared with this method possesses the shell-core structure with the Pt-Sn alloy particles as the shell and the SnOx particles as the core. The electrocatalytic performance of the Pt-Sn/C catalyst for the ethanol oxidation is better than that of the Pt/C catalyst. This preparetion method does not indroduce Cl-. Thus, the prepared catalyst needn't wash and does not induce the environmental pollution. In addition, this preparation method is suitable for the production with the large scale. Therefore, this preparation method is suitable for the practical application. |
