In this study, TiO2 thin film photocatalyst on carbon fibers was used to synthesize ultra-long single crystalline Pt
nanowires via a simple photoreduction route (thermally activated photoreduction). It also acted as a co-catalytic
material with Pt. Taking advantage of the high-aspect ratio of the Pt nanostructure as well as the excellent catalytic
activity of TiO2, this hybrid structure has the great potential as the active anode in direct methanol fuel cells. The
electrochemical results indicate that TiO2 is capable of transforming CO-like poisoning species on the Pt surface
during methanol oxidation and contributes to a high CO tolerance of this Pt nanowire/TiO2 hybrid structure.
