Morphological, Structural and Optical Properties Study of Transition Metal Ions Doped TiO2 Nanotubes Prepared by Hydrothermal Method

Mohd Hasmizam Razali, Ahmad-Fauzi M. N., Abdul Rahman Mohamed, and Srimala Sreekantan
Abstract—Undoped TiO2 nanotubes and doped titanium dioxide nanotubes with various transition metal ions (Co2+, Ni2+, Cu2+) were prepared by hydrothermal method. The samples were characterized using X-ray diffraction (XRD), field-emission scanning electron microscopy (FESEM), transmission electron microscopy (TEM), nitrogen gas adsorption and UV-Vis diffuse reflectance spectroscopy. The structural and morphological studies showed that the transition metal ion dopant was incorporated into interstitial positions of the TiO2 lattice to form a new phase of TiO2 (hexagonal) instead of anatase TiO2 (tetragonal) for undoped TiO2 nanotubes. It could be expected that doped TiO2 nanotubes active under visible light due to their small band gap.

Index Terms—Doped, photocatalyst, TiO2 nanotubes, transition metal ion.
