Reactions of SnX (X = Cl, Br) with [PtMe(bipy)], , (bipy = 2,2'-bipyridine), followed by NaBH reduction at the toluene/water interface in the presence or absence of graphene oxide support rendered PtSn nanoalloy thin films. They were characterized by powder X-ray diffraction, X-ray photoelectron spectroscopy, and transmission electron microscopy. The electrocatalytical activity of the PtSn thin films was investigated in the methanol oxidation reaction. Our studies showed that the PtSn/reduced-graphene oxide (RGO) thin film gave better catalytic results for MOR in comparison to bare PtSn or Pt thin films. A maximum / ratio ( and are the maximum current densities in the forward and backward scans, respectively) of 6.77 was obtained for the PtSn/RGO thin film deriving from the + SnBr + NaBH sequence.
SnX（X = Cl、Br）与[PtMe（bipy）]反应，（bipy = 2,2'-联吡啶），随后在氧化石墨烯载体存在或不存在的情况下于甲苯/水界面进行NaBH还原，得到了PtSn纳米合金薄膜。通过粉末X射线衍射、X射线光电子能谱和透射电子显微镜对它们进行了表征。研究了PtSn薄膜在甲醇氧化反应中的电催化活性。我们的研究表明，与裸PtSn或Pt薄膜相比，PtSn/还原氧化石墨烯（RGO）薄膜在甲醇氧化反应中具有更好的催化效果。由SnBr + NaBH顺序得到的PtSn/RGO薄膜的最大/比值（和分别是正向和反向扫描中的最大电流密度）为6.77。
