摘　　要：The Pt-SnO2 /C catalysts were prepared by two chemical deposition methods.Compared with the Pt/C catalyst a new weak adsorption oxidation peak at low potential is found on the Pt-SnO2 /C catalysts prepared by two different methods.The particle size of SnO2 can influence Pt particle size.The smaller the SnO2 particle size is,the smaller the Pt particle size and the better the activity of the catalyst.Both the catalysts Pt-SnO2 /C(a)and Pt-SnO2 /C(b)have good stability,while the Pt-SnO2 /C(b)has higher activity for ethanol and the adsorbed CO(COad)electro-oxidation.The Pt-SnO2/C catalysts were prepared by two chemical deposition methods. Compared with the Pt/C catalyst a new weak adsorption oxidation peak at low potential is found on the Pt-SnO2/C catalysts prepared by two different methods. The particle size of SnO2 can influence Pt particle size. The smaller the SnO2 particle size is, the smaller the Pt particle size and the better the activity of the catalyst. Both the catalysts Pt-SnO2/C（a） and Pt-SnO2/C （b） have good stability, while the Pt-SnO2/C （b） has higher activity for ethanol and the adsorbed CO （COad） electro-oxidation.
