The effect of Sn for the methanol oxidation in sulfuric acid is investigated using electrodeposited Pt and carbon supported Pt. The preparation has a considerable influence, as the Sn effects range from a small increase to a decrease in methanol oxidation activity. Sn is believed to act through the

Well-dispersed PtSnEu/C and PtSn/C catalysts were prepared by the impregnation-reduction method using formic acid as a reductant and characterised by X-ray diffraction (XRD), transmission electron microscopy (TEM), energy dispersion X-ray spectroscopy (EDX) and X-ray photoelectron spectroscopy (XPS)
The electrocatalytic activity for CO, H 2 /CO and CH 3 OH oxidation of Pt-Sn catalysts has been extensively investigated for a possible use as anode materials for low-temperature fuel cells. This paper presents an overview of the relationship between the structural characteristics of the catalysts (
