(Invited) Fabrication of High-Quality TiO₂ Nanotubes on Conductive Glasses

Abstract

High quality self-ordered TiO2 nanotubes (TNTs) were grown on a conductive fluorine-doped tin oxide (FTO) coated glass by anodization of titanium thin film deposited atop. The result showed that high-density Ti films with good adhesion can be obtained by direct current (DC) magenetron sputtering at 200 ˚C. The dependence of the morphology of TiO2 nanotube on anodization time was investigated by scanning electron microscope (SEM). The TiO2 nanotubes were annealed at 500 ˚C for 180 min, which led to the transformation of the crystal structure from amorphous to anatase. The influence of the anodization time on the crystallization of nanotubes is discussed. The proposed low-cost method for fabricating TiO2 nanotubes provides an approach to enhance the efficiency of dye-sensitized solar cells (DSSCs).

EFFECT OF PRECURSOR MATERIALS AND HYDROTHERMAL TIME ON THE MORPHOLOGY, MICROSTRUCTURE AND PHOTOCATALYTIC ACTIVITY OF TiO2 NANOTUBES

“…So far, many different methods have been used to fabricate the TiO 2 nanotubes including: templating [1], sol-gel [2], electrochemical anodization [3], and hydrothermal synthesis methods [4,5]. A review of these methods was presented in the report of N. Liu et al [6].…”
