Abstract: A green, low-cost and facile strategy for synthesis of SnO<sub>2</sub>-Pt/carbon nanotubes nanocomposites with SnO<sub>2</sub>-around-Pt structure by <i style="">in situ</i> spontaneous reduction of PtCl<sub>6</sub><sup>2-</sup> with Sn<sup>2+</sup> on the CNT surface is reported. The morphology and structure of the prepared SnO<sub>2</sub>-Pt/CNTs nanocatalyst are characterized by scanning electron microscopy, transmission electron microscopy and X-ray diffraction. In addition, energy dispersive X-ray spectroscopy and inductively coupled plasma-atom emission spectroscopy results prove the presence of Pt and SnO<sub>2</sub> nanoparticles on CNTs surface with the molar ratio of Pt:SnO<sub>2</sub> in SnO<sub>2</sub>-Pt/CNTs as 0.48. In comparison with the commercial Pt/C, SnO<sub>2</sub>-Pt/CNTs nanocatalyst exhibits higher electrocatalytic mass activity and better long-term cycle stability for methanol oxidation.
