Abstract

original image

Mesoporous silica templates combined with fast electrochemical deposition provides a means to grow arrays of nanorods 9 nm in diameter and with variable lengths up to a few hundreds of nanometers (see figure). Hierarchical nanostructures of Pt arrays with microscale patterns can be obtained by microcontact printing on the mesoporous silica films.
