Abstract

original image

Perfectly aligned high-aspect-ratio TiO2 nanotubes that are perpendicularly oriented to a substrate are obtained using a two-step anodization process in ethylene glycol containing 0.5 wt% NH4F and 1 vol% HF, overcoming the bundling issue of TiO2 NTs commonly observed in conventional approaches. They are then used as a template for the electrodeposition of Pt nanowires.
