Abstract

Antimony-doped tin oxide (ATO) supported on multi-walled carbon nanotubes as new supports for Pt catalyst (Pt–ATO/MWCNT) has been directly synthesized by hydrothermal method using mixed Sb/Sn hydroxide solution as precursor. The structure of Pt–ATO/MWCNT catalyst is characterized by transmission electron microscopy and X-ray diffraction. The electrocatalytic properties of Pt–ATO/MWCNT catalyst for methanol and CO electrooxidation are investigated by cyclic voltammetry and chronoamperometric experiments in acidic medium. The catalytic activity for methanol electrooxidation reaction shows that high CO tolerance and good stability of Pt–ATO/MWCNT catalyst compared with Pt–SnO2/MWCNT and commercial Pt/C (E-TEK) are observed. These results imply that Pt–ATO/MWCNT catalyst has promising potential applications in direct methanol fuel cells.
