摘要：
A novel tin oxide (SnO2) coated single-walled carbon nanotubes (SWCNT) supported platinum (Pt) electrocatalyst were developed for direct ethanol fuel cells (DEFCs). SnO2 coated SWCNT were synthesized successfully with a simple method of hydrolysis-oxidation of SnCl2 in water at room temperature, then SnO2-SWCNT supported Pt electrocatalyst (Pt/SnO2-SWCNT) and SWCNT supported Pt electrocatalyst (Pt/SWCNT) were prepared by an ethylene glycol (EG) reduction method. The Pt/SnO2-SWCNT catalyst demonstrated much higher catalytic activity for ethanol oxidation reaction (EOR) than that of the Pt/SWCNT.
