SYNTHETIC NANOTUBE TIO2 BY HYDROTHERMALLY AND EFFICIENT PHOTO-OXIDATION OF NO

Abstract

Over the past few years, Titanium dioxide (TiO₂) has become more and more of a commercial photocatalyst popular in several fields, especially in the photocatalytic decomposition of pollutants in water and air. To improve the photocatalytic activity of TiO₂, the synthesis of TiO₂ nanotubes by hydrothermal method was carried out at 135oC for 24h. FTIR spectroscopy results show that the synthesized material has functional groups of the anata form of TiO₂ at the characteristic peaks, and the XRD measurement results are consistent with the standard spectrum of TiO₂. NO treatment efficiency increased sharply after the first 5 minutes and reached 36% after 30 minutes. TiO₂ is a very inexpensive and environmentally friendly material, so this study can lay the essential foundation for the development of doped TiO₂ nanotubes for environmental remediation.
