✦ Synopsis
We present a novel method for the structured growth of carbon nanotubes using micrometer scaled dots of iron doped alumina and titania as catalyst system. To obtain the dots, sol-gel derived inks are deposited on quartz glass surfaces via a novel micro fluid contact printing (µFCP) method basing on inorganic inks and an Ormocer ® hard stamp, and consolidated by a heat treatment. Multiwalled Carbon nanotubes (MWCNT) with and without bamboo-like morphology were obtained on this catalytic ceramic dots using a hot filament CVD process based on CH 4 /Ar/H 2 gas mixtures.
