Synthesis of Titanium Oxide Nanotubes for Photo Electrochemical Cells and its Characterizations

Nano scale materials have many peculiar properties than the bulk ones and have led to break through in various fields of science and technology. Titanium oxide is one of the excellent and most demanded materials because of its various applications and properties such as such as large surface area. In this paper, Titanium oxide (TiO2) nanotube arrays were synthesized by electrochemical anodization of titanium foil. Dimension of nanotubes and elemental composition were detected by Field Emission-Scanning Electron Microscope with Energy Dispersive X-Ray Analysis (FESEM- EDAX). From X- Ray Diffraction (XRD) the intensity of peaks, d- spacing values and phase of TiO2 nanotubes were analyzed. The Energy Bandgap (Eg) of the formed TiO2 nanotubes was determined by Diffuse Reflectance Spectroscopy from Kubelka-Monk Plot. From the obtained results, the synthesized TiO2 nanotubes are suitable for Photo Electrochemical Cell applications.
