Abstract
In this paper, we report on a nonaqueous synthesis of single crystalline anatase TiO 2 nanorods by reaction between TiCl 4 and benzyl alcohol at a low temperature of 80 °C. The resulting samples were characterized with X-ray diffraction, scanning electron microscopy, transmission electron microscopy, high resolution transmission electron microscopy, nitrogen adsorption, X-ray photoelectron spectrometry and UV–vis diffuse reflectance spectroscopy. We proposed that the TiO 2 nanorods were formed through an oriented attachment mechanism. More importantly, these single crystalline anatase TiO 2 nanorods exhibited significantly higher photocatalytic activities than commercial photocatalyst P25. This study provides an environmentally friendly and economic approach to produce highly active TiO 2 photocatalyst.
