| 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. |
