Nano-SnO2 particles were prepared by microwave heating ethylene glycol solutions containing SnCl2&middot2H2O and water at atmospheric pressure. Moreover, the nano-SnO2 particles were employed to synthesize Pt-SnO2/C catalyst. The microstructures of nano-SnO2 particles and catalysts were characterized by means of transmission electron microscopic (TEM), X-ray diffraction (XRD). TEM micrographs show that the nano-SnO2 nano-SnO2 particles are spherical shape with around 2.0nm in diameter. The XRD pattern results showed that the obtained powder is SnO2 with tetragonal crystalline structure. Cyclic voltammetry and chronoamperometry showed that Pt-SnO2/C have much higher catalytic activity and CO tolerance for ethanol electroxidation than that of commercial Pt/C(JM).
