英文摘要in the present work, several carbon supported ptsn catalysts with different pt/sn atomic ratios were synthesized and characterized by x-ray diffraction (xrd), transmission electron microscopy (tem) and x-ray photoelectron spectroscopy (xps). both the results of tem and xrd showed that all in-house prepared carbon supported pt and ptsn catalysts had nanosized particles with narrow size distribution. according to the primary analysis of xps results, it was confirmed that the main part of pt of the as-prepared catalysts is in metallic state while the main part of sn is in oxidized state. the performances of single direct ethanol fuel cells were different from each other with different anode catalysts and at different temperatures. it was found that, the single defc employing pt3sn2/c showed better performance at 60degreesc while the direct ethanol fuel cells with pt2sn1/c and pt3sn2/c exhibited similar performances at 75 degreesc. furthermore, at 90 degreesc, pt2sn1/c was identified as a more suitable anode catalyst for direct ethanol fuel cells in terms of the fuel cell maximum power density. surface oxygen-containing species, lattice parameters and ohmic effects, which are related to the sn content, are thought as the main factors influencing the catalyst activity and consequently the performance of single direct ethanol fuel cells.
