Structure of TiO₂ Nanorods Formed with Double Surfactants

Abstract

Nanorod titania particles of anatase structure with 100 nm length and 20 nm width on an average were synthesized by a hydrothermal process with double surfactants system under relatively rigid tubular template in water. The rods have a tetragonal shape with washboard-like {101} surfaces, and covered properly with a Grätzel dye, exhibiting a high efficiency of light–to-electricity.
