Article Preview

Pt-Sn/WC(O)/C catalysts with different Pt/Sn molar ratio have been prepared by microwave-assisted reduction method. In the synthesis, PtSn alloy was supported on WC(O)/C which was synthesized by the temperature-programmed carburization after the pretreatment of AMT precursor. XRD result shows that Pt particles are reduced successfully. Compared to the reflections of Sn-free sample, the diffraction peaks of PtSn alloy catalysts shift to lower angle slightly. The electrocatalytic activities towards ethanol oxidation reaction were investigated using cyclic voltammetry and chronoamperometry techniques in acid media. The sample of Pt3Sn2/WC(O)/C presents the highest peak current density (332.2 mA/mg-Pt) and stability.
