Preparation of Long TiO2 Nanotubes from Ultrafine Rutile Nanocrystals

Abstract

Abstract The morphological dependence of TiO2 nanotubes on the particle size and crystalline phase of raw materials was observed, and long and uniform TiO2 nanotubes with lengths up to 500 nm were prepared from rutile TiO2 nanoparticles (7.2 nm).
