Pt/C Doped TiO<SUB>2</SUB>/SWNTs as Catalyst for Methanol Oxidation

Abstract

Platinum/carbon doped titanium dioxide/single-walled carbon nanotubes (Pt/C/TiO2/SWNTs) were successfully prepared by blending method. These composite catalysts were found to exhibit an anatase TiO2 structure with uniform Pt/C and the existence of SWNTs can be confirmed by transmission electron microscopy (TEM). The composite of Pt/C with TiO2/SWNTs could improve an enhancement in catalytic properties upon applying TiO2/SWNTs as catalyst support. The catalytic oxidation of methanol of Pt/C doped TiO2/SWNTs is found to be higher as compared to the undoped and Pt/C doped materials.

Anode Catalysts for Direct Methanol Fuel Cells in Acidic Media: Do We Have Any Alternative for Pt or Pt–Ru?

“…Recently, Pt−C mixed/doped with TiO 2 nanostructures and a TiO 2 −SWCNT composite for methanol oxidation have been studied. 258,259 Xiao et al 259 suggested the importance of high porosity and proton conduction of the TiO 2 cocatalyst. The structural and adsorbed water contents in the cocatalyst also affect oxidation of intermediates during methanol oxidation.…”
