Abstract

N-doped TiO₂ nanotubes have been prepared as additives to improve the catalytic capability of Pt/graphene composites in methanol oxidation reactions. Electrochemical experiments show that the catalytic performance of Pt/graphene composites has been greatly improved by the introduction of N-doped TiO₂ nanotubes.

Keywords: TiO2 nanotubes; doping; graphene; methanol oxidation.
