Abstract: Titanium dioxide (TiO2) nanotubes was synthesized by hydrothermal method and calcined at different temperature (300, 400, 500, 700°C) for 2 hours to study the effect of different calcination temperature on the physical properties and photocatalytic activity of TiO2 nanotubes was studied. The anatase phase structure of the TiO2 nanotubes is remained even after calcination at highest temperature studied of 700 °C. However, their morphological structure transformed from nanotubes into nanoparticles after calcination at higher temperature. Hence, reduces the photocatalytic activity of TiO2 material in degrading methyl orange due to the decreases in surface area and porosity of the materials.
