Two-Dimensional Platinum Nanostructures

Yan and coworkers prepared both Pt and Pt/Pd alloy nanotubes using a similar approach [170]. 

Among the porous templates for preparing nanotubes, the AAO membrane is the most frequently used. Yuan et al. synthesized Pt nanotube arrays by using this template via electrochemical deposition [103]. Here, the inner wall of the AAO pores was modified with 3-aminopropyltrimethoxysilane to allow the easy transpart of ionic precursors and release of the nanotubes. The electrodeposited Pt nuclei grew along the modified wall to form tubes. The Pt nanotubes were obtained after the removal the template, using chemical etching.
