Abstract

original image

A nondestructive, simple process for the synthesis of CNT–TiO2 and various other hybrid materials, using benzyl alcohol as surfactant (see figure), is described. ππ interactions enable the use of pristine CNTs without the need of covalent functionalization. Furthermore, benzyl alcohol acts as a growth inhibitor to produce very small and uniform rutile nanocrystals without too great a reduction of the anatase to rutile transformation.
