|Title:||Facile synthesis of SnO2-Pt/carbon nanotubes nanocatalyst with high electrocatalytic performance for methanol oxidation|
|Abstract:||A green, low-cost and facile strategy for synthesis of SnO2-Pt/carbon nanotubes nanocomposites with SnO2-around-Pt structure by in situ spontaneous reduction of PtCl62- with Sn2+ on the CNT surface is reported. The morphology and structure of the prepared SnO2-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 SnO2 nanoparticles on CNTs surface with the molar ratio of Pt:SnO2 in SnO2-Pt/CNTs as 0.48. In comparison with the commercial Pt/C, SnO2-Pt/CNTs nanocatalyst exhibits higher electrocatalytic mass activity and better long-term cycle stability for methanol oxidation.|
