摘要

Well-aligned rutlie and anatase TiO2 nanorods as well as anatase TiO2 nanowalls have been synthesized using a template- and catalyst-free metalorganic chemical vapor deposition (MOCVD) method. Structural analyses indicate that single-crystalline rutile and anatase TiO2 nanorods were formed at 630°C and 560°C, respectively, while anatase TiO2 nanowalls composed of well-aligned nanorods were formed at 535°C. Optical characterizations of these TiO2 nanostructures show that the band gap energies for indirect transition of the rutile TiO2 nanorods and anatase TiO2 nanorods as well as nanowalls are at 3.0 and 3.2 eV, respectively.
